My main problem with this whole thing is that...
We really don't know the first thing about the very nature of the Revolution.
Nintendo refuses to speak about it. So how are we supposed to know if this is a good thing or a bad thing?
Is the Rev a hologram generator? Or does it have some other form of alien video? It seems unlikely, but if it does, it would make sense that this doesn't work with "HDTV". It would have to work with a regular TV (and maybe progressive scan) when it's in "NES/SNES/N64/GCN mode". Which would give Nintendo the chance to make some cruel jokes. There's no such thing as "bad publicity".
Or does the GameCube have a "wireless" TV connection, which Nintendo thinks is the coolest thing ever (and maybe it is), but it isn't up to the task of HDTV support? If that's the case, I'd say that (like the WiFi thing) Nintendo should just put a freaking port on the back of the unit, in order to satisfy everyone. It's cheaper than lost console sales.
Or is the Rev a revised "GameCube 1.5", basically a GameCube with bigger capacity media, a kickass online and backwards-compatibility plan, and a new controller that will reshape the entire videogame industry. All for the low price of $99! And, as we all know, Nintendo is a cheap bastard, and they cut the progressive scan support from the Cube because they did such an abysmally poor job in selling it. So it stays cut from the GCN 1.5.
We really have no idea what's going on. Nintendo's going into this blind, because of their addiction to secrecy. Nintendo might be making some horrible mistakes, the kind where it might have been a good idea to get some feedback first, but we just have to trust that Nintendo's not capable of doing that (LOL!), and that they've got something in the works that's going to be amazing, and can take people's interest from zero to sixty in a timespan fast enough to matter.
