I looked around and saw that no else posted this info so here's a direct quote from the issue in its previews section.
2nd to last paragraph:
"What else did we see? Ah, Assist Trophies! They rock. We were run over by tiny Advance Wars tanks, a giant metroid sucked our brains, and more. Also, a couple of other quick points: thrown items are easier to catch than in Melee, and it is now possible to jump between performing an air dodge and landing."
So I'm assuming now theres a Advance Wars Tank AT and a Metriod AT.
Sorry in advance if this was posted elsewhere and I didn't spot it somehow.
