Well, since we don't know if Ice Cimbers will make a return, I think it's a nice idea to make a similar Dk stage.
Besides, if you look closely, you can see that there are what looks like switches placed upon the platforms... I wonder what those might do.
Otherwise, I'd like to use this chance to say that this thread is the one I have been reading most ever since I discovered this forum, and this will be most likely the thread on which I'll post most of my comments. Even though the original idea behind this thread was to discuss confirmed characters, I have realized that you have also discussed the various updates on the Smash Bros. Brawl homepage, which suits me well. :-)
Besides, my favorite characters to return (which hasn't been already confirmed) would be Peach, Yoshi (although he's pretty much semi-confirmed) and Mewtwo (although I hope they give him a few better special attacks this time).
I'm happy that Wario, Pit and Meta Knight will be there, and the characters I hope will make their first appearance on Smash Bros. are Toad, Midna (riding Wolf Link), Krystal, Diddy Kong and Sonic.
Okay, I hope this will be only the first of many posts on this thread. I tell you, it has really been interesting to follow all of your previous discussions so far.
