So the first three OGN's were not in continuity, right? Adam Warlock is not the Living Tribunal and Thanos is not with Mistress Death! I wonder if these new ones will be similar and not cannon? Also, I'd by anything by these two guys! They are too great to ignore!
They're in continuity technically. They are just noticeably contradicted by other events. Ewing actually makes a reference to LT being reborn in Ultimates, which is clearly a reference to what Starlin wrote. It can be argued that the LT killed by Order/Chaos is the Warlock/LT.
