I'm also very curious to see how Marvel Preview 4 (1st Starlord) does. Its Magazine size, so I wonder if something that silly will turn off some people? Its a rather interesting first appearance for a character that it looks like will be making a big jump into the mainstream consciousness.
Keep an eye on marvel spotlight Starlord vol 2 #6. First marvel "comic book" Starlord. Strange, as this one is the same thing as hulk 271, being first comic appearance of starlord, but has yet to see much action like rocket raccoons first comic appearance...
I think the difference is that Starlord is on the cover of his first appearance. RR is not. Hence the increased interest in #271.
