I'm still waiting for SONY to come straight out and make an official statement about this, one way or another. It seems that SONY is still keeping quiet about FF and they won't comment on "future" features.
After having read the 1Up comment a number of times, I still wonder if it is based on miscommunication. It sounds as if what the SCEA is saying is that, since the palindrome controller can't do rumble without the motors and since controllers never use FF anyway, the controller will just be ignored when rumble or FF would normally be present - it just skips it.
Without SONY being even more clear and forthcoming with comments, we are still left guessing how it is all going to work out. It won't be long, though. With the Euro launch and more racing games about to be released, this question will be answered real soon.
Cheers,
