Avengers A.I. #1 Superior Foes of Spider-Man #1 Those are my Marvel purchases I haven't read yet.
But the real main event is:
Batman '66 #1. Holy Lazarus! It's a perfect recreation of Adam West's show. The writing is spot on, right down to Batman's name calling at the Riddler. Plus, since it's comics, there's more breakneck action that could never have been depicted on the TV show. Jeff Parker really captures the characters to the point where you can hear the actors' voices in your head. I'm so happy Adam West's Batman is back. This Batman is the hero we need.
Plus Batman '66 plays like Marvel's Infinite Comics where it's more animated. For a dollar, it's the best DC purchase you can make this week.
Secret Invasion week also saw some other comic gems. COUNTDOWN TO FINAL CRISIS #04: If you didn't ever think you'd see Darkseid just lounging on a couch in a dingy apartment, well this is YOUR issue! Seriously, this issue's a total crock.
