Ok I've seen Sunstreaker now (you can get to it off of one of the links in this topic), and I disagree with all the "scrawny" statements. It's not as bulky as a lot of tf's, but it's definitely blocky (just in with more human-like proportions). And there's seriously no kibble. It looks like a thinner, more nimble hybrid of Alt Sunstreaker/Mirage. I'm impressed.
