They have to catch up on consoles sold somehow, how many people bought a second 360 when it RROD'd? :)
This is not a trolling post, it is an attempt at humor, with some fact, I know I bought an Arcade when my original 360 RROD'd (Was playing Lost Odyssey and near the end and didn't want to wait weeks to play again) :)
Unicorns ARE real - They are just fat, grey and called Rhinos
