You're actually overlooking one very important thing here; LIMBO. Madara does not have it on that panel when Sasuke cuts him because Naruto is dealing with it. Think for a second, the only way Madara reacted fast enough to Naruto's attack in the first place in this chapter was because of Limbo, without it his defense is not that effective. heck, by looking properly at Madara's expression and words you can see he wasn't too surprised by Sasuke's attack, he just couldn't react fast enough to it but had he some limbo goodness he would've blocked it like he did Naruto's.Seriously, I'm a bit puzzled here. It's sure as shit sasuke's a hell of a lot faster... but let's keep looking at this [You must be registered for see links] here.
Madara was flying away from them at top speed; so sasuke had to cover that distance rather quickly to blitz him. Now, let's neglect sasuke's confusing new jutsu and just assume, for argument sasuke that he teleported towards madara... I don't care about that; What I do care about is the fact that madara was unable to react. Check this shit out...

*Naruto tries here, He almost succeeds if not for ringa [You must be registered for see links]. But i'm not sure if that has more to do with madara still being occupied by the attack he's performing or a true blitz. In any case, kudos to him. But we expect this shit from that rikudou mode naruto's in...
Now, Back to sasuke. Remember the first scan I linked? If you look at it carefully, madara was watching sasuke while sasuke was like 6 feet away or more. So, he didn't get the drop on madara anymore than guy or minato. In fact, he's further away than minato who teleported and needed to swing his arm. Yet, the next panel, he's sliced madara in half. [You must be registered for see links]Notice how madara's staff is still on his side and uncut? That means he never even got the chance to block himself (like against minato, guy and naruto).
Seriously, Thoughts? Because I need to see next week for some explanation of this shit. Sasuke's in base as far as we can tell, with a nice new shiny eye, yet he's blitzing a Juubi jin as good, if not better than naruto? Wtf...?
EDIT: Everyone keeps talking about 'teleportation technique'. AGAIN, i'm not talking about sasuke covering the distance. That could have been teleportation, i don't care. I'm talking about the actual arm swing/forward slash when he was 6 feet away. Teleportation doesn't carry forward momentum great enough to propel madara back.
the only one we've seen speed so great that Madara had absolutely no time at all to use limbo was Guy.
