Gaming is fun, and fun is for everyone
Goodman has done a few "Classic Covers" articles, and although they at times are meant to promote an upcoming product, are mostly just fun articles. They've done Lord of the Rings covers, HP Lovecraft covers, Conan, Moorcock, etc.
So this is probably nothing, or maybe just a "Hey, saw the Dragonlance UA, let's make that our next Classic Covers article."
If it was cross-promotion, I'd probably have saved this for after a Dragonlance OA was actually announced.
