If Nintendo insists on continuing the whole "different from MS/Sony, under-powered companion console, not giving a flip about 3rd party power demand", then they have to do two things to become successful again:
1- Offer something truly different than the competition (a gaming tablet w/possible home dock station is a start)
2 - You have to launch mid gen, or last (up to a yr after comp. releases) so Ninty can minimize the power difference, possibly even be on par/better
Wii U would have been far more successful if it launched in 2010, even 2011 at the latest. Wii U also would have been better off releasing in '13 or even '14, to get their games, OS and power at its best. As you can see, this is how you can screw up launching both too late and too early, at the same damn time (2012).
