The nanometer comparisons refer to the size and distance apart of transistors within the processor. Smaller architectures are more expensive and require a different manufacturing process. It's too costly to come up with a completely new set of chips based not based on the existing manufacturing process and it's also a waste of time reinventing the wheel. The GPU will have to be similar to a 5000 or 6000 series model. It's therefore also very unlikely it will only be as capable as the 360/Ps3.
Studios don't invest hundreds of thousands of dollars of manpower learning it's way around new hardware to produce one off titles on a platform they have no intention of supporting in future.
Development kits aren't free. Early development licenses don't come without stipulations. Existing in-house tools and technologies have to be adapted. Every developer in the team has to learn their way around the new platform which makes progress much slower and therefore very costly. Sure they are getting games that are being released on the 360/Ps3 before the WiiU becomes available. But guess what - the WiiU is getting them, and the other games it'll be getting at the same time haven't been ****ing announced yet on ANY of the platforms.
Wow. Calm yourself. Firstly, smaller chips are cheaper to produce. Here is a
random piece of anecdotal evidence. Yes, it is expensive to create new factories, but once they are created, they can create more, better, faster, cheaper, more efficient chips. Next, you can create a budget card for very, very cheap, and seeing as how Nintendo is going to be packing a freaking tablet in every console they sell, they're going to need cheap systems, so yeah, it will be from the HD line, but the hyper-budget line.
As for the dev units and support and whatnot: same thing for the Wii. Developers devoted teams to the Wii and bought development units and guess what, they made crap games, and not that many of them.
Again, they've done this before, launched an unimpressive demo with a new gimmick, and they're doing it again. I'm saying the last generation is a key and they're repeating themselves. I'm not saying they won't make any good games, just that what has been shown is generic, current gen tech that will very soon be outdone and I have little to no faith in their launch announcement.
