A bit off topic, but I'm surprised people think they will announce the NX version before it is released on WiiU, that will kill it's sales, they will announce it afterwards (similar to GTAV and TLOU:R) like that people will double dip. The NX version will be announced after the WiiU version is released.
On-topic - they might tease it a bit during a direct and reveal it in full at E3.
