So i found this website saying that Shadow may be in Playstaion all stars
translation: -Note i used google translate-
This is just a rumor but still we are also dedicated to news of sonic, so this must publish if or if. Rumor has it that on the official forums PlayStation Network a fan asked if it is possible to come out on Playstation Sonic The Hedgehog All Stars Battle Royale, but they replied that it does not interfere with sales of Sonic & Sega All Stars Racing would pull no Transformed Sonic but a character with clone and that message was a picture of Shadow the Hedgehog? Smash Sonic and Shadow for All Stars Battle?
What do you guys think?
BTW im new here so nice to meet you
