It is probably an announcement of what they are going to do at GenCon.
Of course, one of the pieces of is from a campaign setting article, so I am tempted to think it might announce the next one. Perhaps the articles hint toward which one. Just a guess. (if so, my bet would be Dragonlance, since one of the images was in the Ocean Lance and a lot of talk of clerics, which would also fit. Another possibility would be a high seas setting: the Ocean Lance. Neither of these things have anything remotely to do with the image though so I am not counting on either of them being right).
