For the Europish, South Africanese, and Oceanianites, in the audience: SDK Paint for the Wii U will be arriving in less than a week, on the 26th of February. This build is based on the unreleased v2 for North America that Nintendo of America have been kicking back to us for over 3 months with issues like "Wii U" cannot be broken across lines in the e-manual text (among other ACTUAL issues).
The price will be 4.49 euros (or equivalent), including VAT. (Note that once v2 is finally approved in NA, we are going to end what was planned to be a sale for early adopters of v1, and the price will go to $3.99+tax.)
I am currently in the process of updating http://sdkpaint.com to include all the newest details of v2 in German, English, French, Italian, and Spanish. Some quint-lingual blocks of text have already been put into place, and all images and videos reflect to newest available version.
