chakra. Though, it may grow even more. Either way, I don't think Shodaime would have any idea why it did that since Kyuubi's chakra with its will wouldn't give life force to anything but destroy it.

Defeating Orochimaru however...makes little to know sense based on what we've seen Hashirama do. I say he was given that win mostly due to hype, which may or may not be deserved.
This is actually pretty challenging to take a side on. We haven't seen a true and serious fight of the 1st so to say he would get beaten by naruto is still pretty much in the air. the 1st was able to take on Madara with his EMS and all other crazy shit, and we haven't even seen the true powers of the EMS so it is pretty hard to guess on.
Naruto loses because the Kyuubi will be suppressed thus his main power will be taken out
Orochimaru should be fighting Naruto here most forum member's agreed that Oro won but the lurkers won out
Hashirama would have to catch Naruto before he can supress the Kyuubi right? so I wouldn't render it useless right of the bat. I'm guessing Hashirama's control of Bijuu is like Yamato's except more powerful, so it's not like Naruto won't be able to use the Kyuubi's chakra from the get go.
It doesn't matter though, because Sage Mode makes him stronger and more durable. Not to mention he can still form kickass ninjutsu in Sage Mode, and summon whatever he needs to the battlefield. So he's fine, Naruto wins with just Sage Mode.
This Kyuubi suppression thing is pretty funny, and somewhat interesting, because as far as we know Kyuubi is suppressed, Naruto just took some chakra from it...so I don't know how Mokuton will affect this...
But Sage Mode is pretty much all over Shodai...or at least that's where I'm leaning to
This one is really tricky. On the one hand, Hashirama has the power to suppress Naruto's most potent power, on the other, Naruto may be too fast to catch.
I think, at this point in the manga, Naruto isn't fast enough to dodge Hashirama's mokuton (remember, this is beyond Yamato's, but quite a way I'd say).
So it comes down to a battle of sage mode vs mokuton + all the other abilities of Hashirama.
However, I doubt Naruto has the time to stay still, so I'm giving this to Hashirama, because a) I believe Hashirama would be the victor (for now), and b) to counter the Naruto fandom.
Also, is Tobirama (2nd hokage) in this tournament, or do we not know enough about his abilities yet?
here...for more info read the opening post of the Tournament Discussion thread
I think hashirama would win. He can suppress the power of the kyubi leaving naruto a normal gennin with no significant strength so far. HM would give him a fighting chance but due to its limitations not enough to stop him from getting schooled. Shodai wins.
Like I said in Hashirama's previous match, it's hard to create substantial arguments (i.e. based on feats) for Shodai, since his only feats are as a gimped Edo Tensei controlled by Orochimaru, who was messing around. Naruto, on the other hand, has given us more than a glimpse of his capacity in RM mode now, and thus has quite the advantage here.
However, while it's loose ground to base an argument upon, Hashirama's status and hype should place him very high on the food ladder in Narutoverse. Personally, I'd think that he has the tools (i.e. powerful bodily prowess (speed, strength, stamina, endurance) and techniques) to defeat Naruto, and I also think that Naruto will only surpass him once he has fully mastered his new super mode in combat.
Thus, as of now, I give Shodai the edge: my vote goes to Hashirama Senju.
