God I hope they don't revisit Khan or other villians from the original series. The year is now 2258, which is at least 6 or 7 years before Kirk took command of the NCC-1701 in the original timeline. This is, in many ways, a whole new universe due to the changes to the timeline. I don't want to see a retread of what has gone before. A lot of what made Star Trek XI so enjoyabe was its sense of freshness. Thigns have been rebooted; there is a brand new reality/timeline to play with in which the future is unwritten; let's not revisit/retread villians from the original series and movies. Let's truly see what "new life forms" are out there!
Plus... PLEASE no "Kirk Prime" with a bloated William Shatner...Nimoy pulled off Spock Prime wonderfully...Shatner is LONG past believability as Kirk.
