I heard them play Dan Hartman's "I Can Dream About You" the other day. Nothing really Jammin oldies about that, but it's certainly an AC cut. I also heard Phil Collins as well. Maybe they are planning a transition towards an AC direction, but they've gotta be less subtle than this if they hope to actually attract an audience.
As for rock coming back on 102.7...no way. If CBS really wants to bring back rock on the airwaves in NYC, they'll probably tweak/reimage Jack on 101.1, which already has a heavy dose of (older) rock, or ditch talk altogether on 92.3 if Free FM's ratings continue to be dismal. Then again, you never really know what they'll end up doing over at CBS. I am pretty sure, however, that oldies won't come back (even if I do agree that the format can appeal to a broader audience including younger listeners, if done properly).
