Probably not. It's a great product even without DD involved. Why spend money retooling the assembly line, when it's already a great product. I don't know for sure, mind you, but I'd be very surprised if they're any different.
You're welcome anytime over at the Pro Tools forum.
M-Powered is almost identical to LE. It opens LE/TDM files and looks the exact same. There are only a few things that are not supported with M-Powered, but most of these are just add ons that you purchase separately. And probably nothing that you'll use. You can see the comparisons here.
