First off... Playstation3 is not going to die off or anything. It's currently the most powerful system on the market and it will have some exclusives along with a price cut that will help it out. However, I don't think it will dominate the way PS2 or the original did. It will be a second or third place system most likely.
Secondly Wii isn't going anywhere either. While it may be the weakest graphics wise it's priced right and Hardware wise may very well end up winning this generation of consoles. Software wise Nintendo systems sell Nintendo games. Let's be honest the Gamecube and N64 didn't sell for the strong 3rd party support.
And last but not least XBOX360 might have a minor problem in my area at least nobody touched 360 last holiday season and to be honest with you while I think Halo 3 is going to sell systems the other problems it might have is 1. Alot of people who wanted Halo 3 already bought it and 2. Let's face it everybody who had an XBOX and wanted the upgrade(since it was more or less required) might have a 360 already. Still these are minor problems at best and the 360 will most likely sell very well this holiday season.
Boycotting the following:
1. Yoshi: He ate my car and spit out a toaster.
2. Igglybuff: Totally false advertisement. You can have as many as you like they don't buff nothing.
3. the Terms Hardcore/Softcore... We're talking Video Games. Not Porn.
4. The term Casual as relates to Gamers: We make them sound like outsider's that happen to play games. If that were the case they'd own a PS3.
5. Donuts.... Beacause I drink Beer...... and the biggest fan of Donuts hates Beer.
6. Boycotts: Their so lame.
