Honestly, I'd be fucking contempt with full-on JP support and said support actually making it over here, you can keep your western games, but JP doesn't seem to be as graphics-focused as western companies, only thing is, WHERE ARE THE GAMES?!
Most would say 3DS, which is fine, but I'm waiting on real JP support, we had 2 JP-localized western games announced in the past day (Rabbids Land and F1 All Stars, da fuck), but the real JP support is non-existent. Even multiplats from PS3 would be fine, Dark Souls 2, Armored Core 5, Lightning Returns, smaller companies like say Atelier games (if allowed, I hear they're using Sony's engine, so that won't happen then), Nippon Ichi games, you name it, Wii U's getting nada!
What is possibly going through Iwata's head right now? I remember how gung-ho they were about the 3DS' 3rd-Party support from the get-go at E3 2010. Namco Bandai, Tecmo Koei, and Capcom are the JP devs shelling out ANYTHING, ALL of which are ports...
Nintendo is in MORE than dire need to come up front and announce JP support, because they need a miracle at this point, I'm a believer in their 1st-party output, who isn't, but even Wii had more support at this point.
You said there's a Wii U 3rd Party Direct coming Iwata, well, WHERE IS IT?!
