I think there may still be another year or so until a PF player and 3.5 player can't sit at the same table together.
I think they will always be able to sit at the same table, in so much that any gamers can sit together and play. But I find from the day of release it was different enough that is causes problems. Knowledge of 3.5 is as much of a hindrance (knowing stuff that is actually incorrect because it has slightly changed in Pathfinder) as a help.
