Heh.
We may do a retail box in 2013, it could be possible... But we cannot promise it. (We would need a publisher for it, and retail is a difficult market... but maybe it's possible, we will try for sure.)
Trine 1 sadly is probably not possible. It uses our old technology, so it would take a lot of time to bring to Wii U (or any other platform). Maybe in the (distant) future we'll do a "remastered" version of Trine 1 and then bring it to PC/Mac/Linux and Wii U, but right now we can't make any promises.
In any case thanks for supporting us, and we hope to have the update released in 1-2 weeks.
