notice theres a few things that later appeared in the films -

T3 - 'Don't Do that' and the end attempt to blow up Skynet (including Arnie holding the door open) - it was what audiences was expecting to happen at the end of T3 blowing up Skynet HQ but didn't (so maybe played with that? - like 'ah ha you though we were going to do what you saw in T2-3D ride')

T4 - The T70s are similar to the T600s of Salvation, the way the T800 is killed with its head coming toward the camera similar to Marcus killing the T800 (and again with Reese in TG). plus the idea of the assault on Skynet was also similar to Bale going to take down Skynet HQ (some shots of of him and Marcus approaching Skynet seemed somewhat similar)

TG - the end battle in Skynet HQ between Arnold and T1million sort of mirrored the end battle in TG

pity the future war scenes of T4 (and TG) wernt more like this (although the time chamber was similar)
