I'll speculate on the price of Wii-U when I've got the technical details for the system.
The controller by itself will probably retail for $50, minimum.
I'd wager $60 personally, that controller has to be packing a lot more tech than current basic things like Xbox and PS3 ones, and $60 was the price those controllers were at for quite a while before dropping what, $5 or so? That or your guess sounds about right as well, Wiimotes were around that as well weren't they at release? Wonder if they're gonna bundle a sports game with it as well this time around...
But I mean, think of all the applications a tablet on your controller will give you; all of a sudden don't have to cower behind picking what plays you want to make in Madden with your buddy next to you spying and trying to figure out which of 4 selections you made for example. That alone is a pretty big plus imo...
So yeah, to me Nintendo easily blew out Sony with the Wii U announcement, I mean people already had a basic idea of what the Sony NGP/Vita would encompass, but Wii U being a home console and such, is much bigger news. The controller...well, I thought it looked kinda clunky and big, but we'll see, Nintendo has made some of the best controllers (sans NES and Nintendo-itis) out there. I'm guessing retail price for the console will likely be in the $250-$300 range, you can't really go any higher imo because then the PS3 and Xbox become just as cheap, and odds are that they'd still beat out the Wii U in specs if the past has much to say about it; Nintendo hasn't been ahead in the tech war since what, the N64? And even then Sony PS was better due to the disc format.
My only hope is that they aren't stingy with colors and release the Wii U in something other than a plain color like white; then again, based on how long it took to get the Wii in Black and Red, that's a fanciful dream likely...
