STIV and the new timeline
Obviously I'm overthinking this, but once Star Trek 2009 came out, wouldn't the crew from STIV return to the future of the new timeline?
shareMy understanding (from what I can remember) is that this version of ST takes place in a parallel universe. Or something like that.
The only cross-over is apparently the Spock of TOS ST exists in this parallel version due to some very convoluted reason.
