I found the rest of Saga Legends wave 2 over the weekend.
Both Cody and Rex look very simple, but cool. If they had more paint applications, they'd be great. I don't really mind Rex's skirt as it looks fairly normal from the front. I still want the realistic phase I Rex as this doesn't quite scratch that itch, but it's cool to finally have a realistic, albeit simplified, Rex.
The Stormtrooper is indeed pretty awesome – it's a great sculpt, but again, the paint could be stronger. Not that it needs more details, but it's slightly sloppy on my sample and this sculpt would look even better with tighter deco. At the same time, I don't really remember stormtroopers really ever holding their arms completely straight down at the sides, so it's a trade-off. I'd like to see this sculpt repacked with at least swivel elbows and wrists to hold the blaster properly – then I'd gladly buy way more.
Boba is pretty nice. His detailing isn't too simplified, still including the silver scuffs and dings. He's less bulky than both 2012's Battle Pack version and the Mission Series Jango figure but still requires a little maneuvering to get him into the mini Slave I.
