You probably don't know what the Official Nintendo Magazine is, unless you live in the UK. Whether you know them or not, they've previewed the two upcoming Pokémon games. They've done it slightly different from their other previews, since they've done a 'Top Ten', instead of a general run-down. See the attachments for the scans.
The magazine's website is:

You may have to click the enlarged pictures again, and then zoom in on them to see them properly. Sorry for the quality, and sorry the edges of the pages are cut out!
