Not to be too self serving but I wrote about the Trek Time line in my blog last week. Check it out if you like (link in sig line)
My problem is that even if you take what the writers said at face value and these new movies branch off from the old time line...that creates problems.
If you think the events of Trek 09 take place in its own separate universe...that creates problems too.
The movie dose play like a reboot that erases the old time line and that too is something have a problem with.
