It is a bit harsh to already call a game rubbish, or even compare to the sucky big rigs on what was essentially an 8 minute video. Reserve your judgement for when you actually play the game at least, it still has 4 months or so development time. The video didn't wow me either, but whats the point of flaming it already? On another note, why check out a forum just to talk mess about a game? Seems a bit foolish to me, we all love games, we all love playing games, in the mean time lets give This is Vegas an honest chance for when we actually play a demo of the thing. Until then stop judging a game on a game play vid, and talk on forums of games you actually do like, not on forums you don't. The fact that you as readers and viewers are on this forum talking about the game, albeit it negatively, must mean it peaked your interest somehow, therefore meaning the game preview has done its job.
Whether a game is good or bad doesn't matter, it's how the gamers think of it and how they advertise it (well, mostly the latter nowadays).
That's why games like Okami and Prince of Persia: Sands of Time sat on the shelves "gathering dust" (or just sold a bit "poorly") while 50 Cent: Bulletproof and Jaws: Unleashed sold millions of copies.
