This is early information regarding CoroCoro obtained through one of my sources, while I cannot post actual pictures of the issue itself, I can reveal what to expect this month.

Using a quick drawing program, I've created a rough sketch of the New Pokemon I was shown, a Sableye pre-evolution that's debuting within the Genesect vs. Mewtwo Film. It's a strange, alienoid crab-like creature with a diamond-shell and glowing, ruby red eyes. In the Film, it appears that they're released from their nest in Pokemon Hills during the battle between Mewtwo and Genesect and begin to swam the city. They can fold up their legs and turn into flying saucers as well. Type is Dark/Ghost like Sableye.

In-game screens of the pre-evolution, and Sableye itself, with one battle being Sableye vs. Sylveon. Interestingly, CoroCoro teases at this match-up by suggesting Sylveon has the advantage. Next Month promises additional X/Y Information.

Other major info is a downloadable online Pokemon Tretta program for the 3DS which is a Database that allows you to view information on the various Tretta pucks, as well as use it to locate nearby Tretta Arcades and update you on new sets and such.
