MADL appears to work more or less. The first problem is that it can't talk to anything else. I've also heard a concern that its operating waveband has been assigned to satellite HDTV. This may be rumor, but after the B-2 radar fiasco (its bandwidth also got assigned to commercial satellites, with the result that a B-2 in the wrong place at the wrong time could zap an on-orbit transponder) it is not entirely unbelievable.
Also - nothing new about the gun being unavailable until Block 3F. However, if the stealth and sensor fusion are anything like as good as they claim, any pilot is going to need a lot more luck and prowess getting out of a guns duel with a Su-35 than he demonstrated getting into it.
