The Dark Knight Will Shoot at Liverpool?

Got this news recently from icLiverpool.co.uk, that Robin Higgs, Batman Begins location manager that will also work on the sequel, was in Liverpool yesterday to look for possible locations. Here's a bit of the important parts of that news:

A spokesman for Liverpool Film Office said today: "Robin Higgs was in Liverpool scoping out the city, mainly along the waterfront. He's looking to bring the director Christopher Nolan up at the end of the month. However, they are also looking at Yorkshire, Glasgow and parts of London as well."

Hmm, I'm curious to know what scene that would suit for a waterfront.
