Looks like theÂ Gran Turismo official site was updated today. Ideal if you speak Japanese of course!
The post showing the packaging lists a general March date. Those hoping for confirmation of the date from Famitsu will also be disappointed, as the only GT coverage in this week’s issue is part of a general feature on games readers are looking forward to.
Also there is no confirmation of release date as of yet, so you’ll have to keep looking at the packaging at the moment.
