I'm wondering at this early waking hour..............
If Nintendo was to release a Wii HD that really was a step up from the current system, how would they address those who don't upgrade. As gullible as the non-gamer public has been for the Wii I don't think they'd be so naive as to upgrade to a new system so quick, and I only see Nintendo pretty much making either a refresh of the Wii to support HD resolutions, or a system not so far off from the current spec that developers couldn't create games that could run nominally on either the Wii or "Wii HD". I think the second option would be better for the long term, as it could give the Wii the graphical upgrade so many more hardcore gamers have been clamoring and would last a few years in that configuration. However it leads me to ponder the cost of researching and developing such configuration options. I assume complete backwards compatibility would be necessary for Wii HD.
What do you guys think the best solution would be? I was thinking just another step up hardware upgrading like from the GC to the Wii with some silicon changes like framebuffer size increase. However in my world, the system would have a 45 nm G4 or G5 running at 2.0 GHz, a "doubled-up" Hollywood GPU with much the same silicon accept 45 nm, 300+ MHz, 8 pixel pipes, 8 texture pipes and 8 ROPs, same fixed function T n L and TEV unit for BC with larger eDRAM memory for higher screen resolutions, 4 bolted on vertex shader like units, same 24 MB 1T-SRAM for BC on GPU package, 32 bit z-buffer capabilities, and 256 MB of GDDR3 main system RAM. Sure the RAM seems like overkill, but it's outrageously cheap these days and it's useful if Nintendo wanted to allow people to run music at the same time or run a management system in background a la 360 or PS3. Plus it would open up doors for other media features (as much as I hate them). 256 MB is nice for a web browser. I wonder though, if power management isn't an issue, it might just be easier to just have a whole new GPU and bolt on the Hollywood for BC, in which case I'd put the equivalent of a Radeon 4550 on there. It's a vicious little brute of a GPU, and the desktop card versions use very little power.
Basically I'm going for a double or tripled up Wii here. BC would be preserved, and the ability to run a optimized port of Crysis would be doable!
