I predict another massive price cut ($225 WiiU basic/$275 deluxe) followed by another Ambassador program for us early adopters.
Iwata really needs to step down. I like Iwata as a person but he is simply doing everything either wrong or too slowly and he has been now for 5 years.
The WiiU hardware power, 3rd party support, online services, regularly providing good 1st party games for the WiiU: he has failed miserably on all counts. I don't know what other evidence they need. He doesn't have a grasp of the current market and he hasn't built any relationships with western studios, in fact it seems he has driven them further away.
WiiU should have been "Wii 2". Instead of the gamepad they should have put that money into making it have genuine next gen power (or approaching it) with a standard 10 button dual analog controller (like the WiiU Pro Controller) that also supported Wiimote+.
This is two terrible hardware launches in a row but the WiiU has the bigger problems than the 3DS. Japan won't save them and they have bigger competitors in home consoles.
They will probably give him another E3 where Nintendo will probably give another underwhelming presentation with a few scattered cheers for Smash 4 and Mario Galaxy 3 (or whatever its called) while they spend more than half their time on shit nobody wants like Wii Party U and Wii Fit U.
