This information was sent to me from a correspondent in Japan, who has obtained early information on what the next issue of CoroCoro will obtain, which focuses on Movie 16. This is a transcript of the information he provided me with.
First off, CoroCoro this issue mainly focuses on the star of Movie 16 alongside Genesect, the Superman Pokemon "Duskaman". Duskaman is the romanized name that appears in CoroCoro (and will probably be similar to the English name like previous stars), and its raw Japanese name is Dasukaman (ダスカマン

. Here is the information CoroCoro provides:
Species: "Superman" (Choujin ちょうじん

Pokemon.
Type: Dark/Fighting
Height: 1.9m
Weight: 78.4kg
My correspondent describes it looking very humanoid, with its main stream-lined body being mostly black apart from its white face, white hands, and white feet, and the front of its chest which has a red circle on its chest and another red crescent below it. It has horns on its head which fold back in a "V" shape, and it has a red Mohawk that comes from the back of its head and crosses between the horns and sticks out in the front. It has rather dull looking eyes, semi-circles with little black pupils in them. Finally, it has two red streamers coming from its back that resembles a scarf, but another picture of Duskaman shows that they can transform into wings.
There is the official Sugimori Art included, showing it striking a "Henshin"-style pose, and pictures of it drawn in anime form, including one showing how its scarf transforms into wings. There is also artwork showing it in winged-form flying away from the Genesect Army, as well as Ash and Iris riding Charizard and Dragonite and battling alongside him. CoroCoro talks about how Duskaman is the "night savior of the city", and appears in a flash of crimson red to battle against the leader of the Genesect. There seems to be a connection between the two Pokemon as they're both described as being crimson red. The new title is roughly "The Extreme Speed Genesect X Superman Duskaman (神速のゲノセクトX超人ダスカマン

. The X is actually shining blue, resembling the Pokemon X logo, interestingly enough, while Genesect and Duskaman's names are colored red.
Next issue promises more information on the film, and hints at revealing another Pokemon (unknown if it's in the Movie, the Mini-Movie, or X/Y).
In terms of X/Y information, this issue is very sparse apart from showing the official artwork of the male and female protagonists, and some more screen-shots of them walking around the Paris-styled town, including visiting what appears to be a museum, standing atop the Eiffel Tower-like structure showing a nice view of the of the region, and walking alongside a beach. There's also a look at the new battle screen, which shows that the HP Bars now appear on the bottom screen with little Boxsprites of the Pokemon next to them, and there's two new buttons available as well on the menu which is "Call" and "P-Link", although it doesn't explain what these functions are for yet. There are a few battle pictures of the Starters battling, and also shows that Spoink and Paras are in.
