I got my SS Thrust tonight, and I figured I'd give some quick thoughts on him.
first off, the robot mode is gorgeous. I love the Blitzwing gas-mask head, it looks so great on the mold, and the new conehead piece is really sweet. It adds new character to a familiar mold. Mind you, it does inhibit head articulation, rendering side to side views pretty non-existent.
The colors on this are also really nice. The greens are a good contrast to the creamy color, and it is spaced out enough to be very effective. Outside of the limited head articulation and the gun needing a longer handle to be held proper, I have no complaints about the robot mode.
Transformation is the same as Starscream, but you have to be a bit careful with the new cone, it gets in the way a little bit, but it's not too hard to work around. Alt mode is similarly nicely done and colored, and the greens with the yellow cockpit really shine here. It's just a lot of fun.
In conclusion, if you like the Bumblebee movie, you like Armada Thrust, or you just like fun transformers, get this guy. He is well worth your effort. He's really cool.
