Wifi- $100
HDD upgrade- $120 I think still?
And it still doesn't have an HD-capacity disc medium- $$?
Right there alone the $299 60GB HDD 360 exceeds the price of an 80GB PS3 that has both of those, plus USB rechargeable controllers (no pack needed), web browser, real time global news/weather interface, free network service, swappable HDD's, and a few extra bells and whistles that aren't really needed but are there if you do. $50 a yr for XBL over the course of just four years adds on another $200.
People still say PSN is shit? Maybe when it first started, but even then they had lag free dedicated servers. It's only getting better. They just announced they already have as many users as XBL. The only thing XBL has going for it is....I dunno, more content and a better game invite setup?
I'd take quality over quantity any day though.
Oh and as far as the "console war" goes, Microsoft basically admitted they're going to lose, noticing Sony's momentum. At E3 this year they stated "First to 10 million wins it.", regarding sales in NA. Actually Microsoft, it's just getting started. PS3 is already nearing 10 million in NA and has been outselling the 360 in PAL territories for a while now.
Almost time to rush out another console and screw over your userbase again, huh Microsoft? lol.
