User blog comment:Darknesslover5000/Is Ichigo going to lose his Hollow Powers?/@comment-1590714-20100703101026

Ichigo's Bankai seems to be one that is easily mastered, as all he has to do is fight normally while using it to master it. It's not as if he is controlling a completely different being, like Komamura's Bankai, or as if he fights with something far to big to be useful (Ikkaku's Bankai), so he actually uses his normal fighting style while in Bankai, meaning he pretty much (except for the techniques) already mastered it when he got better at swordsmanship.

Also, I thought an official trailer and a launch site had already been released for the fourth movie. I could be wrong, but I guess Ichigo'll have to keep his Hollow Powers for a while longer. If he defeats Hollow Ichigo, just like last time with the vizard's training, Hollow Ichigo will just disappear into his being again, gaining strength for a new confrontation.

I agree on the Yammy-power-up-release-thingy, although it seems unlikely that he hadn't been warned by Aizen not to use his resurrección there.

Would be fun if Ichigo learned a new version of his Bankai, in which both his Bankai and his Hollow Powers get a mixed form.
