Although the HD remakes for Wii Sports have been sold piecemeal and as a Club pack on the Wii U eShop, there hasn't been a physical release yet for interested parties. According to a tweet from Japanese retailer Sinobi however, that may change.
According to the tweet, a packaged version of Wii Sports Club is headed to the console on July 17th. It'll include baseball, boxing, golf, tennis, and bowling for your troubles. These HD remakes weren't enough to boost Wii U sales, but enough people are enjoying them, I guess.
