A new Batman?

It's all over the net now, but seems to have originated at Australia's Herald Sun.
Apparently, the "industry buzz" is that Christian Bale's Terminator Salvation co-star, Sam Worthington, may be stepping into the shoes of Bruce Wayne in the next Batman movie.

Of course, at this point, any sort of Batman casting rumors should probably be taken with a grain of salt. But I suppose time will tell...
