Update: The Infernape listed in the article below is actually considered legal. There is a way to use the US Walmart code for the HA Chimchar to obtain the Pokemon in other regions. Dream World Pokemon can also be caught in any ball. The Torterra is still completely illegal.

Secondly, it has been confirmed that Pokemon with unreleased Dream World abilities can be transferred to Gen 6, but cannot take part in online play.

Note that these updates come from Bobsplosion himself. I'm just passing them along because he couldn't access his own post, not because I'm being a Pokemon asshole and correcting :)
