I would like to see an ENT based mini-series that deals with the Romulan war. I think the NX-01 should be the ship used, maybe with a few upgrades like a tractor beam and more efficient engine ouput, but NOT an entirely different ship. The entire point of ENT was that is was a starship named Enterprise. Should it be another Enterpise prior to the 1701? Heck no!! I've always reasoned away the whole "the 1701 was the first Enterprise" argument by believing the NX-01 was a "earth" starfleet vessel, and the 1701 was the first "UFP" starfleet vessel to the bear the name Enterprise.
To secure the peace is to prepare for war. -Metallica
