The problem I have had with the whole GC/GBA connectivity is that so far it's almost all geared toward giving the GC game the bonuses. In other words, if you have a GC game the GBA can enhance it a little if you own one. They are going the wrong direction with that. The GBA is having no problem selling, it's the GC that needs the boost. They need to make GBA owners think they need the GC.
They should take their biggest GBA games (like Pokemon) and make it connect to the GC to give the GBA owners incentive to want to buy the GC. I'm not up-to-date with the whole Pokemon situation but don't you need the GBA game to make the upcoming GC game work? I think I read about that somewhere and I think it has potential although I'm skeptical about the connectivity being necessary. Anyway, have a GBA pokemon game, connect it to your GC and all of a sudden you've got new areas to explore and new pokemon to find. Just watch how something that simple begins to sell GC's, especially in Japan.
I can't believe the GC and GBA have been out together for more than a year and Nintendo hasn't exploited this.
But reading that interview, there is no doubt in my mind that I have chosen the best system for me. It's too bad that I don't agree with the mainstream but so be it. Nintendo is where it's at.
