Traveler gets away with this, storywise, by coming out of a futuristic equivelant of the Dark Ages. There tech level used to be higher, but the average is/was around 13. Star Trek technology is equivelant to TL 23+, especially the transporters. In past incarnations there were instances of finding caches of older technology that was superior to even TL 15.
So if Traveler becomes properly supported in D20, something Traveller has never really had, supplements will come out to provide stuff for different tech levels, such as cybertech.
The basis is solid, and it is a fun "world" to play in. If you are tired of the Jedi and Klingon molds, this is definitely a system to consider.
I would be interested in exactly how much financial backing is going to be given to Traveler. If it is still Marc Miller and company it will probably be just more of the same. IE reprinting everything we have been given before in the d20 format. Which isn't a bad thing for us Traveller junkies, but will do nothing to pull in a new audience.
If they are going to try and jumpstart a traveller revolution they better concentrate on totally new material. If this leads to some success then they could intermittently release the updated older material. If they aren't trying to go for substantial market share than they are wasting their time and our money. They need to get us "oldtimers" excited to have any hope of exciting any new blood.
I know their marketing has been pathetic, hardly anyone even knows it is available. They are relying primarily on word of mouth.
So I am unhappy to say I am expecting more of the same.
