Very weak evidence but worth noting
I feel this is most likely a mess up. For one I highly doubt New Telltale is scrambling to get the rights back for Telltale GOTG, so if its anything its probably Marvel who wants it back on store shelves, and even even then I dont see them making anymore physical copies. Telltale's GOTG is really not a profitable investment, so if anything its probably Marvel just wanting to have it up on digital stores to just get a little bit of money.
Still wondering when Tales from the Borderlands is coming back to stores, its almost been a year since Gearbox said they would get it back up. Low key hoping it hasnt happened because New Telltale really is trying to get the rights back.
