You guys need to think about the bigger picture. These consoles aren't even out yet. With a release date of 2006 and a typical life-span of 5 years, these consoles will be around until at least 2011 and beyond (I know I'll be keeping my PS2 and Xbox a few years longer so we might be talking 2012 or 2013). Sure 1080p and dual HDTV outputs seem excessive now, but with the speed at which HDTV technology is improving and the price of HDTV sets dropping, I wouldn't be surprised if everyone has like 2 or 3 HDTVs in 5 years. The other thing to remember is that Sony's primary market is still Japan and in Japan they've been using digital TVs for years already. That's where the whole dual monitor thing will catch on first, then eventually the US and Europe so Sony might as well include the feature. Hell if you think about it, the Xbox and PS2 have HDTV capabilities but it wasn't until the last year or so that people really started using them. By no means is it mainstream but it's deffinitely gaining momentum.
Bottom line is, I'd rather have the feature than not have it especially since it's doubtful that it'll affect the overall price.
