Egyptian perhaps, but (Russian) MAK have a worldwide reputation and I would not for one second hesitate to accept their findings.
Personally, I'm still waiting for the final report on Tatarstan Airlines Flight 363 (hull loss with 50 fatalities in November 2013.) It's been almost two years, there has been no report, and the whole thing seems to have been either forgotten or intentionally buried by MAK.
They can do a decent job if they are allowed to, but there are no guarantees that they won't be told to manipulate conclusions / sit on evidence for political reasons, and there are no reasons to think that they'd refuse to cooperate.

I saw the pic of the tail cone a page or two back..was there definitive HS seen?
I noted a pic on another site (no source) showing what looked like a stab in the middle of a huge burned area....does that seem right?
I thought the primary scorched area of debris was wing box and forward fuselage?

While looking at the altitude graph given by FR24 we should assume that data received by different ground stations is exactly what aircraft sent. Also there is no question about 4 station suddenly loosing correct timing.
Thus we see exactly what aircraft altitude sensors registered. If we speculatively exclude possibility that there was some electromagnetic disturbance that invalidated analog signals from altitude sensors, then these pressure fluctuations were registered at altitude sensors. One thing that could cause such a crazy fluctuation is an unusual attitude of altitude sensor port regarding airflow.
Also, sensors and computers and transmitter still had power and plane was still almost in one piece despite crazy attitudes.
It could be that there is not much useful data on CVR and FDR if breakup started from tail part.
Huh... now I speculated enough and have to stop

Is this really almost routine?
From the AP,
"We are all shocked. It was a good plane. Everything checked out in 35 minutes," the official told The Associated Press on Sunday. The closest the plane came to being in trouble, he said, was three months ago when the pilot aborted takeoff halfway through because of a system error. "That's almost routine though," he said.
Was it ever confirmed that the crew did or did not request to divert due to technical difficulties?

more sooted pieces
There is a RT video from forward part of wreckage shot from helicopter, it looks from there like wreckage is mostly undisturbed. At least bigger parts of it lie where they landed. No signs of heavy moving equipment around.
That suspicious piece of wreckage, can anyone identify where it belongs to?
It really looks like it got its fire damage before landing.
There is another suspicious piece with external soot on it. I identified it as a fuselage piece just from under second door. (from cockpit)

@thcrozier:
"What % of transport aircraft suffer tail strikes and are subsequently repaired and returned to service during their service lives?"
This question is very much on my mind today. We know of two terrible accidents in Asia attributed to failure of an improper rear bulkhead repair.
If (as now seems somewhat likely) the Metrojet catastrophe may be added to this list, then the major aviation regulatory bodies around the world will surely be pressed to take a fresh look at the hazards of major damage repairs to such a critical airframe structure.
If anyone has, or knows how to find, data on the frequency of tail strikes and the "distribution curve" of consequent repair efforts, I would be very interested to see it.
How many RBH repairs, versus how many "time-bomb" blow-outs years after the repair?

Corners
Looks like you have three corners of the aircraft in one area, and the fourth further away.
As always, I'm stating the obvious, but it always helps me to simplify things :-)

This photo of EI-ETJ was apparently taken in May of this year (sorry, can't post picture): Photo Metrojet Airbus A321-231 EI-ETJ
Does the bottom of the rudder look quite as it should?

Tail strike frequency
Possibly an initial phase of a structural failure simply allowed the tail section to flex in response to pitch inputs which would quickly make pitch control problematic both for the computers and the crew.
Attitude excursions would add to the forces flexing the remainder of structure between the fuselage and tail until it came off at which time power and data would likely be lost to the CVR and FDR.
CVR noises just before breakup should allow investigators to distinguish between structural failure and explosion.
It will take time.

I count 57 on this list, which runs from March '07 to August '15.

So call it 5 a year. I would hope the frequency is decreasing given modern Cockpit Displays. Still, it would be interesting to compare failure rates in repaired vs never damaged aircraft.
on the pictures of the broken off tail section, don't you see a couple of doors behind the break line?

So we are yet to have any idea where the HS is located?
Note: the piece of wreckage marked at 30*08'52"N 34*11'24"E on the satellite image COULD be it, but the resolution is not good enough to tell for sure.
