Ah.. was totally busy this week and just saw these pics now.

To be honest, he looks great, better than the original MP prime, merely because of the small changes. The truck cab looks much better for one.
The bot mode looks less stocky and more proportioned. The extra detailing on the grill and nicer cartoon head looks great. Add to all that the proper trailer and you have a winner.

It is tempting for me especially since besides MP grimlock, I don't own any other MPs- and this prime looks so sweet. Having said that, $250 steep. Ill wait to see reviews...

Hopefully this means an ultra magnus (with trailer armour) is in the works. Id buy that.
