Good article, though the thread and article titles are a bit misleading. They were worried, but obviously aren't anymore.
Here are some quotes that I liked from the article:
"...the raw processing power is impressive."
"We were positively surprised by how efficient the SPUs (the Cell processing units) were to do such things as run our vegetation simulation, our animations or our physics systems."
"The hard drive and Blu-ray are making our life easy considering FC2 is an open world continuously streamed around the player. That streaming bandwidth and disk space is very appreciated. So, in terms of AI, game structure, physics, dynamic time of day, open world gameplay, dynamic weather system, destructible vegetation, all of those things where we had really pushed the envelope technically, they run well on PS3."
