Mario and Kingdom Hearts?

I don't own this picture. I just found this picture on google. Mario belongs to Nintendo and Sora belongs to Square Enix and Mickey belongs to Disney. I was like woah, woah, woah, woah, woah, woah, whoa. "falls back on chair" it's a cool picture especially with Mario with a keyblade. it's not the kingblade, the one that mickey has, it's a different keyblade cause if you look carefully at the end of Mario's Keyblade Keychain, it's a starman. and plus, it's too good to be fake. on some website, it said it is a game. i'm like amazed but i wonder when it comes out. do you think it's real, or fake?
