Terminator timeline @ Things Of Interest

For the purposes of this timeline I am using information solely from the movies The Terminator, Terminator 2: Judgment Day and Terminator 3: Rise Of The Machines. Information from other sources is ignored, since the production of Terminator 4 is likely to do the same.

T3 explicitly acknowledges that there are multiple timelines in the Terminator universe. I have managed to pare this down to a conservative one timeline per movie, plus one initial timeline.

Terminator: The Sarah Connor Chronicles is said to provide an alternate sequel to T2 and therefore occurs in a separate timeline from T3. I'm waiting for more information before incorporating it below.

Timeline A

This timeline is not shown in any movie.

Sarah Connor conceives John Connor by an unknown father. [John Connor may not be a genetically identical individual in each timeline; he is, after all, played by a different actor in every appearance.]
Skynet is researched and built, from scratch.
Skynet becomes self-aware.
Judgment Day occurs.
2029: John Connor leads the resistance against Skynet.
In a last-ditch attempt to avert its own destruction, Skynet sends a T-800 back in time to assassinate Sarah Connor before John Connor is born. John Connor sends Kyle Reese back in time after the T-800. These two temporal incursions create Timeline B. The assassination attempt fails.
Skynet is defeated?
