In a surprising turn of events coming off of the Beta leak Superbot entertainment accidentally posted these pictures after updating their website a week ago showing several characters from the supposed leak, including Raiden from Metal Gear Solid Rising, Rachet from Rachet and Clank, Sackboy from Little big Planet, and Nariko from Heavenly Sword. In addition several yet unrevealed characters are also shown in the artwork including what looks like Cole in his outfit from Infamous one, Jin and Kazuya from Tekken (both of which were deconfirmed via famous Marvel vs Capcom Player ClockW0rk, one of the developers of the game on Neogaf), and Ryu Hayabusa from the Ninja Gaiden series.
While it might seem like Superbot is acting careless with all these leaks, perhaps there is another aim. Recent comments from the developers have hinted at more content beyond the initial beta leak (the code of which is over a year old). It might be feasible that Superbot leaked these images intentionally to get people excited and guessing. Nothing like adding a little more uncertainty back into the equation as we wait for more reveals (the next 4 of which are occurring at Gamescom tomorrow, the 15th).
The initial leak turned more than a few would be purchasers away with such choices as New Dante (or as some call him Dino, Dante in name only), Raiden, and Evil Cole McGraph (clones in a smash clone!?). Such uncertainty could help get people interested if there are in fact more characters as the developers seem to suggest (I’m looking at you Tomba). In addition, the beta will be updated with fresh code closer to release in Fall of this year.
