Actually I stand by all those points.
- Higher resolution does benefit most any game. It can make a crappy game look cleaner (if you're going to play a crappy game for whatever reason, hey at least the image quality is nice), and it can make great games even greater. Combined with enhanced horse power they allow (most importantly) the best designers and best artists a broader canvas to create more expressive worlds to immerse the player in without less compromise.
You can see the Dolphin emulator that works on PCs that can take GameCube and Wii titles and run them a HD resolution -- in virtually every case, the game looks noticably better on the emulator, in some cases (like Resident Evil 4) dramatically better. RE4 running at 720p from the GameCube build (no changes in lighting or textures or anything) looks almost like a 360/PS3 game. You can see texture detail that was intended by the artists that wasn't possible to really pick on using the lower resolution.
- It's quite possible because of cost/performance issues, Blu-Ray or some minor variant on Blu-Ray will end up being the format Nintendo uses because it's a widely manufactured and easily scalable technology. Not a lock, but certainly a fair possibility.
- Nintendo has said all along that they will offer an HD capable successor to the Wii at some point and that they are not anti-HD from day 1.
You want to argue against those points, be my guest.
