Hang on a minute. If you will recall, Ichigo's new hollow form had a FACE, rather than a mask, i.e. the mouth could open and speak(or well, shriek, in any case). Chances are, Ichigo has already attained his resurreccion, but does not have control over it. We have no idea about the method of hollowification used to convert Tousen. Another point that I cannot quite grasp is whether Tousen (and maybe, the others) hollowified before the Soul Society Arc or after. Sure, they did not have the Hougyoku, but we do not know for sure if that was even involved in the process. Plus, gaining hollow powers before the events of that arc would also explain the perfect control that Tousen has on his hollow form. Remember, the Vizards (save Kuna) had to train for a really long time (unspecified, but making an estimate using Ichigo's growth rate) to perfectly control their powers. It is unlikely that Tousen could have mastered it in a few months. All this is speculation, of course.
