It's not ideal but at least it's real BC and we get to play all our old games right away and at no extra cost unlike the Vita.
Yep. Here's kind of a big point people should keep in mind:
Sony - start with hardware BC supporting nearly all PS2 games, then remove it to re-sell customers HD collections and a handful of emulated PS2 games via PSN.
Sony Vita - get rid of UMD drive, no UMD trade-up or discount program, customers rebuy all PSP games via PSN, but at least the quality of the BC is superb, they did get that right.
Microsoft - make sure Halo 2 works at launch even with major graphical glitches, add a few dozen Xbox 1 games, abandon working on emulation leaving many games glitched or partially functional.
Nintendo - provide free importing of all Wii digital content, make sure everything works 100%, entire library playable outside of a couple of games that used a dance pad accessory.
... and Nintendo is the "stupid" company. No, not really.
Again, wait and see exactly what Wii U does in Wii mode. See if the system is internally upscaling the image BEFORE it goes to the TV, to output either a 720p or 1080p image, essentially, over HDMI. Quality could very well be superior to most / any TV scaler.
Remember, upscaling is NOT upresing or re-rendering. Nintendo said from day one Wii U would only render Wii games at the original 480p resolution internally. Hardware BC PS3s, for example, do not re-render PS2 games at 1080p, they just provide an optional blur filter to slap on top and upscale the low res image instead of letting the TV do it.
PSP games on Vita look good because Vita's screen is an even multiple of PSP's resolution, so when the PSP image is upscaled (not re-rendered) it isn't ripped apart by odd multiplier scaling artifacts.
