From all the “gibberish” I read on Japanese sites, I found that there is going to be some Sonic merchandise at the Tokyo Game Show this spring. The T-shirts are priced at 3,000 yen, which is about $21.50 U.S.
There are also wallets which are about $20.79 U.S. (left) and $12.90 U.S. (right), if my calculator isn’t lying to me.
