Well, look at it from Nintendo's point-of-view. Durango is rumoured to have a monumental 16-core CPU paired with one of the latest ATi/whatever they're called now GPUs. The PS4 (less specific) is rumoured to have even more under the hood than this.
Microsoft and Sony have this market to themselves. You already know that, at launch, you'll probably be paying £400 or something for either of the new consoles from these two. Maybe £300 if you're lucky. Even then, MS and Sony will be making losses. However, they know they have the market and audience for that kind of thing.
Nintendo, on the other hand, do not. They started really losing this crowd all the way back with the GameCube. Nothing wrong with the machine itself, and power-wise it sat right between the Xbox and PS2, leaning more towards the Xbox side.
The GC, while profitable, lacked a lot of the kind of games that the then-maturing gaming crowd wanted, in addition to their Nintendo classics. I will always love a good Mario game, but I love a good GTA as well. I'm 26. At the time of the GC launch, I would have been 16. I think I was nearer 18 when I actually bought one.
Anyway, Nintendo let this 'problem' grow and grow. They kept pumping out solid Nintendo games, but that wasn't enough. The third party presence wasn't what the ageing gamer craved, especially when he saw what the other consoles were getting.
All of a sudden, the GC became this weird market where certain types of games did very well, whilst more mature games on GC were totally-outsold by those on competing platforms. The GC then stopped getting these kind of games.
Then comes the Wii, which to this day I think is just a repackaged, overclocked GameCube with new controls. I saw literally almost no difference in graphics. OK, so Twilight Princess has a couple spots on GC where it would drop a few frames, and didn't run in widescreen. Big whoop. Even then, how much is thjat down to Nintendo trying to play up the Wii hardware? I'm sure the GC version could have had widescreen.
But the real issue with Wii is that, aside from certain JRPGs, you really only have Nintendo to look towards for proper games. Even then, we're talking your classic Nintendo wholesomness. Nothing wrong with them, solid Nintendo gameplay, but it isn't enough for a serious gamer in his/her 20s.
Mature games were thin on the ground, and when they did appear they were usually tat like Conduit, which while seen as a godsend on Wii I'm sure, would've been seen as a pile of wank on 360 or PS3, even if the graphics were on par with the best.
Ultimately, Nintendo are in a place where they have secured a whole new market for themselves, but lost a great deal of the old market. They have said that they know this, and that's good.
But really, can they actually dig themselves out of that place and win back the rest of us that they lost? I look at Wii U, and again, I'm seeing nothing to suggest that this isn't basically just current-gen hardware with a new controller.
I could buy a Wii U and get a slightly smoother Batman: Arkham City or whatever, or I could hold out for PS4/Durango which by all accounts are going to be much larger leaps from the current crop than the 'U.
So it's all about waiting and seeing, and obviously the games. ZombiU looks cool, but it's obviously a project resulting from a Nintendo coming to their senses and going "We need a mature game for Wii U! We will pay you this amount, and you will make it!".
One game is not enough, nor is the addition of slightly smoother games I can already get for my PS3/360.
