It was said that PS3 would be supported at least until the first expansion, after that they would see what happens. Yoshi-P was extremely vague, and it had the feel of someone telling people what they wanted to hear even though he had absolutely no intention of doing it. Take it as you will, but considering that FFXI STILL supports PS2, I don't think SE will have the balls to drop it no matter how much PC players complain about it.
