Seriously, I've heard enough about this piece of shit to know I won't be happy with it.
These idiots should have picked one or the other: a straight prequel or a straight reboot.
Whatever they decided to do, they shouldn't have done this: http://screenrant.com/images/enterprise-first-thumb.jpg
and try to imply to hardcore fans that this is supposed to be the same ship we saw in the original series.
Just pick a prequel or a reboot and stick with it.
As for Nimoy being involved and the storyline involving an "alternate timeline via time travel", that's just an attempt by TIIC to try to placate and blow off the longtime fans at the same time.
