After close to a year of silence on the matter Shigeru Miyamoto says Pikmin 4 is still happening. The legend spoke to Game Rant in which he said the game had "fallen down the list of priorities" in the wake of NX and other projects...
“Yes, you are right, and we’re working on [Pikmin 4]. So, you know, when we’re in development we have to create a list of priorities and it has been hard to kind of fit that into that list, but we’re hopefully starting to see that on the list now.”
Last year we learned that the game was close to completion, so is it possible the game is being further tweaked for NX compatibility? We heard Miyamoto say a couple weeks ago that NX missed E3 to "prevent imitation" and that new technology was getting looked into, maybe Pikmin 4 is being reworked to fit the new mold that NX is creating? Maybe I'm getting my hopes up too much.
In either case, it's good to know that Pikmin has not been shelved. Is it possible we won't be seeing it on consoles though? I wouldn't mind 3DS...or even mobile installment!
