1) Wave 2 is out now.
2) There'll be a Wave 3 and a Wave 4, plus more beyond that. It ends in 2019.
3) The people in these threads are usually very bitter and bitchy, don't take it too much to heart and remember to like what you like and let them dislike everything.
4) Recommendations for Power Of The Primes: All the Dinobots. Including Slash. Especially Slash, Slash is cute and well done.
Beachcomber. Cheap, he's a fun old hippie character, and he's pretty well put together.
Elita-1 and Jazz are good. Jazz is harder to find because some asshole snuck "MAGA" into his decals so they had to halt production and rerelease him. Elita-1 is a swoll girl.
Starscream is pretty disappointing since even though Elita-1 and him share most of the same parts they look worse on Starscream, but some people like him. Make your own decisions on that. Swollscream still has some fans.
Some people are disappointed with the Terrorcons AKA evil Dinobots, but once again you should make your own decision.
I like Moonracer, she seems to have less fans here. Her armor kinda makes her look pregnant, and she has like no butt or shoulders, but I don't see it as a problem.
This guy has good reviews if you find a fig on his page, he's a bit hyperactive and his opening bit isn't necessary, but he does a good job covering the basic pros and cons to each figure and compares them alongside others. He doesn't seem to have any Wave 2 stuff yet. https://www.youtube.com/user/emgo316/videos?disable_polymer=1
