Codito Development is bringing this modern board game classic to the iPad. Theres no word on exactly when Puerto Rico is going to hit the App Store, however Codito has confirmed that the game has been submitted to the current rights holder Ravensburger for approval. Expect this one to hit the iPad first, followed by a release for the iPhone and iPod Touch at a later date.
This was submitted to Ravensburger for approval around the 13th May. Given that Tikal has "a few problems" I guess they are giving it a thorough going over.
