It might just be the things we already know plus the demo release date. It's way too early to release MH4G at the moment. The release of  that pilot trailer for MH4 two years ago was meant to boost sales for 3DS, making gamers like us sure that the MH franchise is not going anywhere else in the near future and it's safe to buy a 3DS without any doubt. At the time being, it's too early to release any news about whether this game is going on to another platform or getting an upcoming sequal. Both of these news would make an impact to sales, and it's quite unlikely that Capcom or Nintendo would be happy with that.

My best guess is they will be releasing news about the upcoming of MHFG on WiiU along with this particular Nintendo Direct.
