What I think will happen: I think Surfer vs. Thor as we expect it to happen probably won't or if it does, it will be inconclusive. A hammer shot here, a cosmic blast there. I think Odin/Galactus will be where the action will be.
What I want to happen: So long as it's a good fight between the top two dogs in Marvel, I'll be happy. While I consider himself more of a Thor fan than Surfer, I do acknowledge that Surfer could beat him one-on-one just as much as vice versa.
I am pulling for surfer in this one but I think it will be either inconclusive or thor will win. I mean his movie is almost upon I highly doubt they'd have him lose right now. But I am holding out here because I was caught off guard completely and how easily he beat the snot out of Bill in his own book.
WW Hulk vs. Sentry was a pretty good fight where they went all in. It was uninterrupted to boot. Most fights in general in comics are too brief for the comic vs. enthusiast.
Considering the fanbase for both Thor and Surfer and the general consensus that they're the two most powerful heroes in the Marvel U, this should be getting more hype and build up then the grueling build up to Thor vs. Sentry.
logically, seeing as surfer has had some power ups while thor got depowred and lost the odinforce, surfer should theoretically now be above thor since classic thor was about equal to surfer back in the day. and now we have classic thor vs a post annihilation surfer.
