Im a big Wandy fan, but I think Bisping has a decent chance.
I dont think he will repeat the 'circle the wrong direction, towards his opponents power' strategy.
Assuming that to be the case, he can remain elusive and stay outside of the pocket and bruise up Wandy's mug enough for 2 rounds... then in the 3rd, step in, do damage, then get out quickly.
The problem with Wandy is that he has gotten really flat footed, he's not as nimble as he used to be.
That said, I still hope Wandy lures him in and drops him like he did Jardine
