I just got £28 for it trading it in against the 360 version yesterday evening.
I doubt these issues will affect it unless it reaches national newstand press levels (when its truly in the public consciousness) which is very unlikely. You'll probably find most employees in game shops won't even be aware that the game is out as they tend to be more clueless than your average pensioner about videogames

.
I'd imagine for a good few months you'll get a very good return for a trade-in on such a new high profile game.
