^ That doesn't make sense...
How could it be 1973 when the timeline was changed AND when Trask released his first version of the Sentinal, an invention that likely took years to design, develop and release?
No, something would have had to happen prior to 1973 to affect Trask himself, making him want to devote so much time and energy into the deveopement of the Sentinals and everything that goes along with that (inhibitor collar, mutant tracking device, etc.).
If we assume that the original timeline did not include the Sentinals (since we have seen nothing about them as of yet that would indicate they have been around since 1973) then something had to change the timeline to get Trask to develop and release the Sentinals. Somehow the government would have had to be affected to fund Trask and purchase his robots. Since it wasn't until X2 or X3 that we saw such a hightened mutant hysteria, and there were no sentinals to stop the mutants, then that timeline did not have them. So something changes in the past to make Trask and the government develop/fund/release the Sentinals. That's the originating change. Yes, Wolverine will likely be sent back to stop the release of the Sentinals, but that couldn't be the original change to the past, right?
