The fighting game will be sold both at retail and as a download in Japan. However, the downloadable version will take up 16.7GB of memory.
The standard Wii U system only includes 8GB of internal memory, so if this is an indication of the typical Wii U retail game's size, the system is inadequately equipped to download even a single game.
There is also the Premium Wii U console, which features 32GB of internal memory, of which the single game would use more than half.
The Wii U has an SD card slot to expand the system memory, and Nintendo has indicated that external memory can be used through the system's four USB ports.
Nintendo has said that its first-party Wii U games will be available both at retail and as downloads in the Wii U eShop. Third-party title availability will be determined by each publisher, with Tekken Tag Tournament 2: Wii U Edition being the first third-party game confirmed for downloadable release.
The download will come at a discount, priced at 6,280 yen (£49 / $78) rather than the retail price of 6,980 yen (£54 / $87).
It is unknown if downloadable Wii U games will carry the same discount in Europe and North America. On the Nintendo 3DS, games released both at retail and in the eShop have so far carried the same price.
The Wii U will launch on November 18 in North America and November 30 in Europe. It is expected to experience stock shortages at retail in its first month.
