Sony has yet to announce November's free PlayStation Plus games, but looking back at a blog post from early September, it was discovered that The Binding of Isaac: Rebirth will be one of the next month's free PS Plus games for PS4 and PS Vita.
Rediscovered by Gamepur, producer Tyrone Rodriguez confirmed that The Binding of Isaac: Rebirth "is the PS+ November game for North America and Europe."
The Binding of Isaac: Rebirth is set to release on November 4, which also happens to be the first Tuesday of November — typically when the new lineup of PS Plus games are made live. We don't know what games will join it as November's free giveaways, but Sony typically releases two PS4 games, two PS3 games, and two Vita games. At this rate, though, it looks like Driveclub PS Plus Edition, which was originally slated as an October PS Plus game (but was delayed), will be a November release as well.
Assuming November's PS Plus lineup is made live on November 4th, we should expect some sort of official announcement from Sony next week.
