Well I seem to remember a while back.. a long while back.. that Square Enix basically said they would do a Kingdom Hearts once they were done with Final Fantasy and other projects... if I had to hamper a guess.. I think Square still has that attitude.. for all we know a KH3 has been in the works all generation in some form or another.. but they are just now.. really starting to show it off.. and take it seriously... I think it's going to be years... before you will see another Kingdom Hearts because of their priority series.. (Final Fantasy) I also think by the time it comes out.. they might be forced to make it for all 3 consoles.. (Which is why I don't mind it taking so long) Square can sit back right now.. and take a look at how the current gen is unfolding.
Nintendo Wii by generations...
2. Wii U
3. Wii O U
Predictions made by gamers concerning the current Nintendo line up of games.
Pikmen 3= Little Bump to nothing. (Got Little Bump)
Wind Waker HD= Won't sell anything (The explosion happened here and at one time 4 Wii U games was in the Amazon top 100)
Super Mario 3D World= Won't help at all looks cheap. (Currently the most sought after Wii U game and continuing the Wii U increase.)
