It was claimed by some site a few weeks ago that Tarantino was cutting lots of time from IB. But this is what Harvey Weinstein has to say about that in the latest GQ:

“Those stories are all untrue. There’s no fu**ing way. Here, read my lips: That is nuts. Please don’t even write that, it’s insanity. There’s not even a question of that. Whatever you’re reading, it’s like some insane blogger… There’s no truth to any of this. He’s not gonna cut. What he’s doing is just reorganizing some scenes. I mean, the guy had six weeks to cut his movie [for Cannes]; most guys take six months. Most guys take a year.

When I worked with Martin [Scorsese], we’d do eighteen months in post-production. Quentin Tarantino cuts a movie in six weeks? Come on, there’s sh** on that cutting-room floor that’ll blow your brains out. I was telling Quentin the opposite-”You should put that sh** back in the movie.” There’s scenes with Brad Pitt and the Basterds, and I’m praying he puts that sh** back in, ‘cause it’s un-fu**ing-believably great. Listen-this movie will be between two hours and twenty minutes and two hours and twenty-seven minutes. I don’t think it’s going to be shorter-it’s just a question of rearranging. I know he’s putting footage back into the movie. I know he’s got some cool sh** that he didn’t get time to address.”
