Wasn't sure how new these are but they definitely weren't there the last time I visited MW's actual website. Some of the pages for their rides have new backgrounds.

GL:

Batwing:

SDSC:

SE:

WWF:

DC Rivals:

and

Arkham Asylum:

I think they are a nice new touch.

Most of them have been there for a while, however from memory, the GL and SDSC ones are new, along with the DD one (which isn't anything exciting, but better than nothing).

And a few other interesting ones for the kids rides and HSD2.

Okay @JaggedJanine, they are definitely new.
