This week's Nintendo Download, however, brought news of the first true Cross-Buy opportunity on Nintendo systems. If you buy Squids Odyssey on the 3DS, you'll be able to play at no extra cost on the Wii U (you cannot buy the Wii U version and get the 3DS version free as of yet however). We appreciate that on the surface this does not appear to be massive news, but to our knowledge it is the first time that this has been implemented across Nintendo systems. It's worth noting, however, that this is only the case in Europe with this title, initially, but will likely be included in North America in the future.

I like cross buy for my Sony systems, this also seems like a good feature for Nintendo to have as well.
