Evolution Studios's Driveclub was scheduled for release last November at PlayStation 4 launch, but was pushed back in the eleventh hour forcing Sony to change their PS Plus plans (Contrast filling its spot in the Instant Game Collection). Since then we haven't heard anything about when it could possibly see release. Naturally we assumed it would be early in 2014, but the Italian Official PlayStation Magazine now claims it will be released in June. A long wait, but hopefully it will all be worth it in the end.
Update: This rumour was given more backing as retailer Newegg lists the release date as June 24. Perhaps we're due for an official announcement of the release date soon.
