My save file is over 7MB and still haven't noticed anything drastic(few bugs here and there and some 5fps slow down when i ride a horse) but i herd the problem is with the ram because Skyrim saves areas you've been to on it and all you need to do is restart or give your console a rest every few hours to reset the "saved areas" on the ram.
But i don't like to keep my PS3 on for longer then 3hrs with at least 2 hour break anyway (im paranoid and i still have a fatty)
I wouldn't let this stop you from playing it dude CAUSE IT'S FREAKING AMAZING!!! this bug may not even affect you. OR you could just get it on steam
