I think it's too late in the game for cross gen games. Most cross gen games are announced before the new gen launches or shortly after.
Not necessarily true. Take Call of duty for example (albeit, activision is pretty transparent on that one). Also, Sony has expressed interest in keeping the PS3 alive longer than they kept the PS2 support going into the PS3 era. I'm not sure about MS's stand on the 360.
But to answer the TC, I'm starting to think about the possibilities of the now current gen hardware and how amazing it could be. Split gen games are notorious for holding back current-gen capabilities because the focus is split. I'm going to want to start seeing the true power of the new consoles.

I believe MS has stated a 2 year committment from the time the One released, so maybe another year and a half? However, that doesn't necessrily mean that devs will want to take advantage of that support. But they certainly could.
I disagree cross gen is killing games right now because although the newer consoles are more powerful game developers have been using that power to make individual hairs move and fish to react to you instead using the added power to make there worlds more immersive and there campaign's longer/better.
