Recently I've been playing them on Dolphin with my ripped ISOs. They're WBFS but it's nice to have them playing in emulated/upscaled 720/1080(very laggy) for me. This of course is only for single player, but it's great for games that I've never quite gotten to completion and having the opportunity to finish them. I think the Wii will stay around for quite a bit longer. Not everyone wants to shell out ~$350 for a Wii U, or perhaps they want the GC backwards compatibility of the Wii. It would be awesome if the Wii U was modded and was able to play Gamecube games with the pro controller. There probably won't be another revision after the Wii Mini (What more could they possible take from the console to make it cost less?), so no real advertisement, but It will probably still sell higher than the Vita.
