This will have been lost in the shuffle, but the developer of Aixom Verge posted this over at US Gamer a bit earlier:
I got a piece of good news today that indicates I might be able to have Axiom Verge ready for NX at launch...but basically that was as far as my source even knew. So I still have no idea what the system is like and still am reading sites like this to try and guess.

Interesting in itself. It reinforces a few things:
1) We may well be seeing far more indie support at an earlier junction for NX, as suggested by Emily.
2) Things are moving in the dev world for the system (so were likely to get more reliable leaks/speculation over the next few months).
3) If there was still any doubt that NX will have a regular control scheme, between Zelda and indie support, its all but confirmed.
Yes, NX won't be at E3, but there will still likely be a lot of rumbling in and around the event, given behind closed doors meetings and such.
