Nexgenwars hasn't updated sales yet. All those figures are weeks, maybe a month old. Ok 5 factors left for the PS3 to survive.
1. Launch in Europe needs to go well.
2. They need to keep MGS4 PS3 exclusive (They practically lost everything else for exclusiveness)
3. Pray the 360 doesn't do the $100 price drop.
4. They need to drop their game prices at least $10.
5. They need an online gaming network like X-box live. I hear the Wii is getting one in a few months.
