ChainsawAsh said:Apparently, T1 and T2 are 100% canon with "Salvation," but T3's events, while they happened, won't be followed as strictly (i.e. some elements may be retconned or just not mentioned).
Sounds like what they did with the Jaws movies. Jaws 1 & 2 had been cannon, and the only thing carried over from Jaws 3 to Jaws 4 was that Michael Brody was studying ocean sciences.
