In the Architect scene, on the monitors, when The Architect mentions that Neo loves Trinity and the screens starts showing her, you can see scenes that will be shown within next 2 min - Trinity is fighting Agent.
This can't be previous versions of the Matrix as the previous ones didn't have Trinity (I think?). Hmmm, now that I think about it, Trinity could have been in previous versions and everything could have played out same way on all versions of the matrix. Just in previous ones Neo didn't love Trinity... But then many things would have played out differently in original Matrix movie, and only Neo was engineered... Any thoughts?
