Frankly the entire console war is a bust since PC has the strongest game line-up and following.
But since this thread is about 360 vs PS3, I will straight up say that the PS3 still has a massive chance of 2nd place this generation.
1. Sony is finally getting rid of the multi-SKU crap and focusing on one.
2. released their Greatest Hits collection which means some games are $29.99 versus $59.99.
3. Improving upon their system through updates to the PSN and PS3 firmware.
4. The HD format war is over and Blu-ray is starting to eat away at DVD's market share. As the PS3 receives price cuts or upgrades instead of price cuts customers will see greater value in having a game console with a build in Blu-ray player.
5. Releasing great first party exclusive titles as well as having strong 2nd/3rd party support.
