Hey I'm also switching from metal / plastic minis to Lego for all our PathfinderLITE
I looked at a few sets when I was at Wal-Mart. They look cool. I don't care for the extra gamey bits like the Ninjago stuff but whatever; I don't have to use it.
The minifigs look rad though. Love the new heads, torso / leg designs, new pieces, etc. etc. Some of the sets looked like a quick way to get several rubber tank treads which I'm lacking.
So I really don't care about the Chima line, its story, or whatever.... I just like the new pieces =)
