I wonder if games with framerate issues will be improved on this.

The games weren't designed for HD output so it probably wouldn't have made that much difference anyway

Doesn't bother me too much. Thought it would be nice.
Ever since I got my HDTV on Christmas, my Wii games look a little less spectacular.
But it's okay, I learned to deal with it.

I'm not 100% sure if Reggie meant what I think we all assumed he meant in that video. He was talking about how game assets (textures, HUDs etc) would need to be reworked to make a game HD and that that can't be done on the fly. In those Dolphin Emulator videos and screenshots that everyone likes to point at the HUD draws attention to itself in all it's very non-HD-ness.

Personally I'd almost rather the game be not HD if that's what people mean by making games look HD. If we're just talking about using the Wii U circutry to upscale and possibly Anti-Alias (to remove processing and lag on the TV end) then I'd have much less of a problem and... I don't think that's what Reggie was talking about.

No upscaling isn't a massive problem IMO.

all scaling would do is give you a slightly sharper and clearer picture with fewer jaggies and, depending on your tv, it could cut lag a little. nintendo's console will probably do scaling anyway since it's bound to let you change the resolution output so there's no reason not to upscale the old games. what reggie's talking about sounds like the full enhanced emulator treatment though.
