Icelandair Boeing 757-200 (TF-FIA, built 2000) experienced right main gear collapse on landing runway 10 at Keflavik (BIKF) in very stormy weather. (up to 56 kts) None on board flight #FI529 from Berlin-Tegel were hurt. METAR BIKF 071530Z 13042G56KT

Second part of the video shows the landing from the collapsed side https://m.youtube.com/watch?v=ILdwSl...ature=youtu.be
It looks like the gear collapses at touchdown (which appears to be relatively smooth) and the spoilers restow almost immediately, either by pilot action or failed air-ground sensor of the collapsed gear. It also appears the pilots pick the right wing up until the airplane slows down and then it drops again.
Rumors are the the collapsed gear was recently overhauled and fitted less than 3 weeks ago...

The wind condition could favour a case like this, the groundspeed would be way less when the wing finally settles.
And Keflavik has crossing runways, and is located on flat land, so they often operate in quite strong winds. Problem comes with the air gates, and deboarding passengers when the wind picks up.

Probably !
From the first picture, looks like that the collapsed gear did not move rearward, it only moved outward, so as you rightly say, the Side Stay might have been the weakest link.
What is also peculiar from the first picture, is that because the right side of the aircraft is actually sitting on the engine, therefore something that is more forward than the gear itself, that in turn results in some weight being added to the rear, behind of the point of support. It is quite noticeable that the Nose Gear is very extended, indicating that it is not much weight is sitting on it. Still, that is a lot better than if it would be sitting on the tail.
Rwy 10, Wind form 130º, therefore half of the wind intensity is Crosswind.
As mentioned above, this is a very windy place. Went there a few times during a summer years ago. On one occasion after landing, taxing to the gate, parking brake On, even completing the after flight paperwork proved to be a bit difficult as the aircraft was constantly oscilating due to the wind.

That right main gear door hanging down indicates to me that a problem occurred during the L.G. extension sequence and was not related to touchdown forces at all.
Just my opinion.

I suspect that when the gear gave way, the engine would have impacted the runway with a pretty substantial thump, which could well have been sufficient to dislodge the gear door.
