I'm kind of disappointed that the 3 new Racers are just there so King can have his own version of the 5 (as he perceived them) contestants who thwarted him in the previous season.
They've got a smart lizard, a hotshot rookie, and a pink-hued amazon with Krom and Axle continuing to act as foils for Sunny and Tamira. Criticise OoAa, Cuckoo, and Wrecks all you like, but at least their gimmicks were quite distinct from everyone else's. It also takes a bit of fun out of the race when it's now boiled down to Autobots vs Decepticons surging down the tarmac; the loss of the free-for-all competitiveness, you know. Traitor foxes notwithstanding
Still, I really enjoyed the last season and hope they keep things consistent while fixing the bits of it that didn't work like the speed and impact of the hand-to-hand combat scenes.
