Good summary Johnknight. Gives me hope for the Wii U. Still haven't bought one.
I'd like to add it gives hope to Sony, too. Both consoles could sell over 100 million units IMO. If Nintendo slips up or even just has a tiny period where they have no real big name exclusives, Sony could "take the lead" or at least gain a lot of momentum with the PS4.
That could happen Sony gets say MGS5, MGS: Ground Zeroes, Uncharted, a new take on Jak and Daxter (which should happen; that IP was an incredible experimental combination of platformers and shooters that I think would be great to reintroduce now), Ratchet & Clank, or really anything Naughty Dogs makes, they can really get some momentum.
Sony showed some maturity with the terrible PS3 start. Hopefully they truly did learn from that and learned that just because they were on top doesn't mean they can go and party when they're on top. No, champs gonna train and train and improve and improve in order to keep that belt, and since the start of this generation they haven't been close to the belt at all in regards to home consoles.
It would truly be great if Sony and Nintendo learned from their mistakes with their last consoles, bring back what worked in previous generations, and gave a great effort going forward with this generation. Overall however both companies have made great games and consoles since they started (regardless of how underwhelming consoles like the PSP and GCN performed, all of them were worth owning and then some).
Hopefully Microsoft learns, whether the easy way or the hard way, that in order to sell game consoles, you have to put gamers first, because quite frankly, they aren't even close to doing that with the Xbox One. All they have in it is a giant confused mess of a box that does nothing that some other box already does better.
The Xbox 360, PS3, Wii, DS, and PSP, all while rocky at times, especially at their starts, were great consoles. From the looks of it, Sony and Nintendo seem to have a great plan in place that shows the company's collective maturity. Microsoft, however, took the opposite route. Of course, all that can change with time.
