Nobody who knows (Adobe employee or Beta tester) is allowed to comment on future products
Tell Adobe what you want... the more requests, the better chance of a feature being added
I agree with John T, as anyone, who actually knows, has signed an NDA, and are barred from commenting.
We will just need to wait until there is an offical "sneak peak," or the release of PrE 11.
Steve Grisetti, our MOD/host here, usually does an "officially sanctioned" article, "What's New," but it comes very close to the release date, which is historically late Sept, early Oct.
I realize that does not help you make some choices now, but I know of no way to get such info.
Now, some magazines, and Web sites do "leak" some details (not sure how that happens), but often those are from early beta versions, and might not accurately reflect what IS inside the release version - things can change, and change greatly in any beta software.
Good luck, and wish that I knew more.
In Premiere Elements 10, there is a project preset for DSLR 1920x1080, 24 fps (23.976) progressive. If it's not in version 11, you should be able to pick up Version 10 somewhere.
