I doubt this. The main differentiator between facebook and myspace is that facebook is clean and easy to use, vs. the maelstrom of crap that's tossed at you in myspace. If they do allow widgets, I'd imagine they'd go the opposite route as myspace: instead of allowing all widgets and sites except the ones they block, facebook will probably only allow sites that are approved.
