The RPGA/TSR newsletter Polyhedron focuses on a new TTRPG that was coming out at this time focused on the Marvel Universe Superheroes. It’s an interesting yet short lived game.

In terms of D&D content there is the usual adventure module which I will cover more in depth when they are published as their own stand alone module,  but there are also a couple of articles about the game.

One of the articles by Roger E. Moore covers the conversion of characters from one system to another and a James Ward article covers the archetypal magic user. As usual Polyhedron is a pale shadow of Dragon magazine, but you could still scour it for interesting stuff once in a while.
