since yesterday after i read siege # 3, a doubt cross my mind. 
after osborn told sentry to bring it all down we saw the sentry flying trough asgard to bring it down. 
the first time i saw that, i thought it was thor hitting sentry as we see thor saying"no" and we see a panel of thor with his hammer in hand about to hit and the we saw a ball of fire through the walls before asgard crumble.

i dont know, i think that scene its ambigous as , i thought at fisrt thor was hitting sentry and they give us the sound thor makes when he hit.  i could be wrong i dont know.
 i didnt really get that part. please i need opinions of what you think happens or what really happens.

  You're talking about the Sentry v Thor
 
Sentry won that first round...or round 2 depending if you count their very 1st encounter
 
I don't buy Siege anymore, I pre-order about 5 comics and Siege is not one of them. The rest of my comics are random issue or TPBs I missed
 Siege is not my thing anymore but I will pick it up and flick through it
 
Ok here's how I interpreted it 
Sentry shows up all Superman style and boasts Yo I'm so super I'm more superman than silverage Superman so how many Gods do I have to kill today
Thor doesn't hang around to debate, he dashes straight in and unlike Ares he seems to have hurt Sentry
Wham he hits the Sentry hard with the hammer, one of Thor's best shots and the Sentry drifts back a little
 
Thor is shocked to see the Sentry still standing and gasps saying something like "Odins Eye" or some "Wow I never knew he was so silver superman" stuff
 
Thor goes one more time Wham! The Sentry's body looks messed up but he's still ready to fight Thor, this weird lobster tentacle thing pops out of Sentry and then starts to grab Thor 
 
the Thunder God got surprised,  that weird tentacle lobster thing looks as if its going to asphyxiate Thor or eventually break him
suddenly the scene changes, old Tony Stark Ironman says hello to the new Iron Green Goblin
Tony flips a switch and suddenly some mega hacker shut down thing happens. The Iron Green Goblin's suit is about to be taken apart like fragile vase  
 
Goblin screams no  F-you Ironman if I go down a bunch of people come with
 
destroy it all, 'Bring it all down' 

The Sentry/Void drops the ThunderGod he is choking, flies into Asgard and nukes it as if it were nothing more than a target in the desert
 
Thor looks like a little boy thats about to break down in tears
 
Asgard looks nuked
 
That's how I recall the fight
 
 
As much as I think Thor is a way better character with far better stories, Sentry won that fight no matter what 
 
The fight was a let down
The Siege arc an even bigger let down

thank you for sharing your opinion. 
i dont know about the fisrt round you are talking, i mean in the first issue thor one shot the sentry, but anyway.

thank you, for clearing this up to me.  
jaja i thought thro somehow break sentrys grasp and he was hitting the sentry , that why he was saying no... like a thought he was in a trance, liek in warrior madness, now i see the look on his face was more like importent, because he coulndt do anything. man really whata let down. this just proof the only person that can writte thor properly( with th exception offcors, of the people who wrote classic thor story arcs) is jms. bendis doenst really get the character. 
man, i hope in the last issue thro get his revenge and kick sentrsy ass or voids, goes all warrior madness and beat the hsit out of it. i thiunk sentry is lame, another superman wannabe

Thor blasted Sentry/Void with some major firepower and it did jack s#!t to him, he floated there and took it and didn't even say ouch.  Then Sentry/Void closes the distance and grabs Thor by the face, but before he does anything to him, Osborn tells him to "bring it all down," so Sentry/Void drops Thor and golden bullets Asgard again, this time destroying the whole city, breaking it apart and bringing it crashing to the ground.  All while Thor stands looking awestruck and shocked.
