What ever happened to Tim Burton's Frankenweenie Remake?

It's been awhile since we've heard news about Tim Burton's remake of his short film, Frankenweenie, but Producer Allison Abbate (who is working on the new movie Fantastic Mr. Fox) assures us it's still in the works, but far off. Two years is the estimate, but when it does start filming it should be done around London, and it seems at this time that it'll be done in Black and White like the original (hooray!) and possibly in 3-D.
