I know this month's CoroCoro probably won't have something new, but you never know. There's still nine copies (maybe ten if X and Y come out in the 2nd half of October) So instead of make a multiple topics on the newest one, might as well combine them all.
Just as a timeline for when CoroCoro leaks, it usually leaks as early as the 8th and as late as the 14th.
Personally I think we MIGHT get some trivial new bit of info, but I feel like February's issue will just give us what we already know......maybe things aren't going to be revealed from CoroCoro this time because of simultaneous releases. We'll have to find out once Feb's issue comes out.
(1/11/13) - February CoroCoro reveals only the official art of Xerneas and Yveltal.
(2/11/13) - New Eeveelution, Ninfia (or as some people might call it, Ninfeon)
