Since the last update I have read:
from Incredible Hulk – Pardoned: Incredible Hulk 282-285
from Essential Peter Parker The Spectacular Spider-Man Vol. 4: Peter Parker The Spectacular Spider-Man 75-79
from Thing Classic Vol. 1: The Thing #1 (note: as best I can tell this probably should be read before Fantastic Four 251, as the suggested reading order I am using plops it right in the middle of a multi-issue FF adventure in the Negative Zone)
(NEXT PLANNED: starting Incredible Hulk – Regression, back to Epic Iron Man – The Enemy Within, more Peter Parker The Spectacular Spider-Man Vol. 4)
