/me throws logic out the window.
Sasuke will definately get stronger, along with Naruto and gang. The question now is, what does Orochimaru have to gain by giving him power during this 3 years? If he's only after the blood line limit sharingan it would be pointless to give Sasuke any power at all because we all know that Orochimaru isn't interested in his hatred for Itachi. Unless of course he wants to risk having Sasuke killed by Itachi.

Another possiblity is that by making Sasuke stronger Orochimaru can also gain more strength when he eventually takes over his body.
