I like the flashbacks in TenTen. All the most annoying characters are off screen, although I do miss Bob.
Spoiler:
They can't see Rukia's soul, because shinigami are supposed to be invisible to anyone who isn't dead, but after Rukia gets the fake body, they should be able to see her just like anyone else.
Ichigo is supposed to be really special, being able to see her while she's on duty, but I think everyone who ends up on the 'squad' has that trait as well - Ichigo, Orihime, Chad, and Quincy Archer. I also suspect that older of Ichigo's little sisters (the one who refuses to admit that she sees the ghosts), and the Childhood Friend (tm) will both eventually develop powers to match the rest of the characters.
And, of course, Don Kannonji will defeat them all with one hand tied behind his back, because he's cool like that.
All in all, I'm looking forward to it.
