Gabe Newell says the PS3 is a waste of everybody's time

[NJ5]

Kwaad, all developers would prefer to program without being forced to use threads. And they would especially prefer to not program on asymmetric architectures as the Cell is... Seriously, Sony took something which is already hard and made it even harder to work with on the PS3.

For that and other reasons (e.g. bad tools and APIs, too much memory overhead from PS3's OS), don't be surprised to continue seeing developers watering down PS3 ports until the PS3 builds a decent userbase (if ever).
