Yeah, this "list" was originally mentioned a couple issues back in Insider - and although I don't know that they mentioned Chewie, they did specifically say that "you'd be surprised to know that Han isn't on the 'A list'". I think that the reason sited was he wasn't as popular with kids, which is surprising to me (although they do seem a little more into prequel/CW era stuff overall). It did sound like when they say things like "the hero figures are selling well", they are talking about others (Han/Chewie) outside the "A list".
Like Jeff mentioned, it pretty much sounded like "well, since the lightsaber battle was the only good thing about TPM, a lot of kids like Qui-Gon, Obi-Wan, and Maul"
. Like everyone has mentioned though, for Qui Gon being so A-list, he sure hasn't gotten many releases. The very nice Evolutions figure is making it back out in the mail away this year, but I'm surprised it wasn't put into Saga Legends yet if he is so high profile to them.
