OK...
Aside from all of the BS about dice type...
I still have issues with some of the tech.
Those Aslani, and Human robots look like somthing that we can create now..
As a computer engineering student (actually, it is Mechatronics/AI, which is essentially robotics) I think that this is going to rapidly become an issue.
Especially when Toyota, Honda, and Ishiguro's Company (I cannot recall the name) bring their robots on-line and into the market in 2009 - 2012.
They are pretty advanced by even today's standards.
Also, the Aslani Robot doesn't have the digigrade stance of an aslani...
Aside from that... All I am really interested in for T5 is the miniatures rules, and producing a line of miniatures.
Since it is Mongoose doing the miniatures... I will bet that they will be 25mm, which chaps my ass. While I like 25mm for skirmish. I hate them for doing massed combats. I prefer 15mm and 6mm for larger battles.
I am hoping that my concept of multi-scaled minis for the various types of miniature play will still be viable.
You're probably doomed to be disappointed on several fronts. First, Traveller is an RPG/homage to the Golden Age of Sci-Fi (1950s-1960s). It is not, and will not be, an RPG that models current Sci-Fi trends. If you like Golden Age sci-fi (like me), then Traveller should work for you. The converse is true as well.
That may not be all bad, by the way. I like studying what sci-fi authors predict and how accurate their predictions turned out. Excluding handwavium (FTL drives, reactionless drives), I've found that science fiction authors are wrong far more often than right. I think that we tend to congratulate them on the 10% they get right and ignore the 90% that they got wrong to some extent.
In particular, science fiction authors have repeatedly failed to accurately project the implications of personal computers. Even sci-fi that came after the personal computer revolution seems to under-predict (or extravagantly over-predict) computer tech. I recall a scene in the novel "3001", in which a protagonist sends an email (that goes directly into the recipient's brain), but makes typos because she can't type fast. Keyboards...on computers that plug directly into the brain. Or, the failure of Cyberpunk authors to predict wireless networks (rectified later, I'm told).
Conversely, some authors have overpredicted things like flying cars, nanotech and some cybertech.
And even recent sci-fi can look dated now. I think that a truly current sci-fi game will have to be revised annually if it's gonna accurately reflect sci-fi thinking and take into account current technological developments.
Even then, the author will probably get most things wrong. So your expectations may be a bit unreasonable.
And as a veteran game master (28-29 years and counting), I'd observe that most ultramodern tech makes adventures far less challenging. Cellphones, the internet, Google Earth and GPS can suck most of the mystery and challenge out of a situation. And highly capable robots would make it unnecessary (and foolish) to send people into dangerous situations. No fun there.
So I like the retro-tech flavor of Traveller...because it's more fun. And at the end of the day, I play RPGs to have fun.
YMMV, of course.
Second, 28mm is the scale of choice these days because skirmish gaming (popularized by Warhammer 40K and similar games) uses that scale. And in a world of limited resources, you really can't blame Mongoose for preferring the most popular scale. Especially when they already have an extensive 28mm sci-fi line in place.
Regarding 15mm, check out Ground Zero Games' 15mm line. It has a very Traveller-friendly look and includes vehicles, infantry, etc. Item V15-20A is a *very* Traveller-esque grav APC. I note that GZG often has the same vehicle/troop in 1/300, 15mm and 25mm scale. Brigade models has a complementary line of 15mm vehicles as well.
Quick Reaction Force produces a nice line of modern 15mm vehicles and troops. Many of them can easily impersonate sci-fi vehicles (switching turrets is an easy way to disguise a real world vehicle), especially non-grav vehicles.

As for rules, well, Stargrunt and Dirtside (Ground Zero Games) are highly regarded. I personally don't care for them, but many folks like them. Either is far better than Striker or the abysmal Striker II.
FWIW, I will be revising Railgun:2100 after I complete "A Fistful of TOWs 3" (my modern miniature rules). Railgun 2 will have a very strong Traveller flavor. Plus, I'll have a conversion system so that FF&S weapons can be rated in Railgun/FFT3. FFT3 will be out this year, so Railgun 2 will be out in 2008.
