It could be, but given the fact that fallout 3 and I believe Fallout new vegas had some timed DLCs first on 360, I find it unlikely for fallout 4 to be exclusive. If it is however, that would be awesome, I am a huge fan of the fallout series and although it wouldn't be mind blowing, it's still a pretty awesome reveal.
I'm still thinking its Final Fantasy VII remake, a Crash bandicoot reboot, Kingdom hearts 3 or some sort of MMO.
