If i remember correctly, they said there won't be any more Meego devices even if N9 will be successful. Though, It won't surprise me if it won't be the last, considering how many times now they changed their plans.

Personally, i hope someone else will pick up Meego as i'm done with Nokia, at least until their plans become more "permanent". With all this strategy switching they don't even have a working platform now, only WP7 somewhere in the future.
