Just read about this on TUAW.
Looks like they have redesigned the bamboo tray part of the case. Looks a bit better than previous generations. The 330% number seems like a big claim but the originals weren't all that strong so we'll see.
Apparently available from today.

I'm on the fence with DODOcase. I bought one from their summer collection and it hasn't exactly aged well for me. Decent case but not sure I'd invest in a second one.
