As we all know by now, Vanquish developers Platinum Games are taking the the torch from Konami to finish Metal Gear Rising, because they failed to do so.
Kojima at first, considered bringing in a Western developer after first planning on canning the game in late 2010. But since Raiden is a ninja(originally from Japan) he later decided that a Japanese developer would best be able to deliver a true ninja game.
An almost that never will be. What Western dev could of created Rising? Bioware? Sony Santa Monica? The world will never know.
