So no, the Wii U is not the next PS3. I don't see ANY sign that Nintendo has learned the lessons from the last generation that Sony did. They have NOT planned for the future. They have NOT built the infrastructure to continually turn out 1st party Wii U software.
I'd argue that Nintendo has done a better job of planning for the future than both Sony and Microsoft because Nintendo is the only one of the three that has a business model that revolves around turning a profit as soon as possible. They're in a far better position to face hard times than their competition. Now, this isn't to say that Nintendo couldn't be doing more. However, they're doing okay considering the circumstances. Wii U had a rough start, but it's in a decent position to be profitable for Nintendo within the next year. They're stubborn in many ways but not completely clueless. While they clearly hoped motion controls would be more sustainable, we've seen them move away from it so they've shown some degree of self-awareness.
I find it strange that people tend to give more credit to Sony than Nintendo considering how much money Sony's games division lost last generation. Sony operates mostly on a "We'll make it back later" philosophy. It's a slow process, one that consumers don't see. Sony lost a lot of money and while Sony eventually made money on PS3, they haven't made up for those losses. They have done a better job with PS4. I read that the bill of materials is approximately $380 so they're probably losing less than $100 this time.
Both Sony and Nintendo could stand to be more balanced in their approaches. Nintendo's is safer which I consider better since it
allows for greater flexibility in the future regardless of whether Nintendo actually does anything with it.
However, I feel like when Sony steps up to the plate, they swing for the fences. They may swing and miss, but at least they ****ing try. They still experiment and play with ideas and strategies that might not work, and the results are often at least interesting. Occasionally, they're amazing.
I don't see how you can rightly say that when Nintendo bet their console future on motion controls. I don't even particularly like motion control games and I even hated it in Skyward Sword, but as it stands, this is pretty much what you're commending Sony for. It's just not the way you wanted it which is understandable, just unfair to claim Nintendo isn't doing this.
Sony has reduced the Vita and PS4 to a more expensive version of the Wii U.
Sure, Remote Play kind of gives PS4 feature parity with the GamePad (note I didn't say Wii U since PS4 is more feature rich), but your statement is ridiculous to the point of parody.
