they got scared when the played rolando 2 and saw how good it is, so they pulled it! Only joking! If they are developing a "true rolando killer" then I expect it will take some time to get right.
The only thing that will kill rolando 2 is.. Rolando 3! Aha nah I don't know if chillingco will be able to publish a game that beats it, but they might.
Whatever Chillingo releases, hopefully they do a thorough job of QA. That's usually their biggest problem.
Maybe they already released it, but it was so terrible that they were ashamed to admit that it was the rolando killer. haha
__________ killers generally end up committing suicide before they ever actually kill anything. See: Every iPod "killer" ever released.
