Hopefully they'll come up with some great extras.
Yeah, I'd like to see extended editions of episodes or some re-edited feature-length. Alternative to the individual shows as they count in the canon, I'd stress.
Since seamless branching involves opting in to something different to a default setting, howabout an alternative title sequence without "Faith of the Heart". Perhaps Archer's theme and "Space... the final frontier" monologue as once seen on startrek.com?
Anything I'd suggest would undoubtably be prohibitively expensive though.
Like filming a better final-finale involving a cast reunion and an elderly Archer attending the launch of NCC-1701, before he pops his clogs the next day.
