That's the unmarked spoiler thread, and no one is using it!
I was re-watching the end cutscene in Starcraft 1 between Dugalle and Duran + Kerrigan, and my god, Kerrigan oozed so much personality in Starcraft 1 as the Queen of Blades, just the way she talked was awesome. I also miss old Zeratul, but can't do much about that.
On a spoiler related note, does Nova say anythingdifferent to Jim if you helped her in WoL? I helped Tosh and she brought up that I didn't help her otherwise she'd look the other way. There was also the other time when you're going to go rescue Jim, Horner mentions they were going to send in Tosh, I wonder if that happens if you didn't help him.
I'm still annoyed they didn't bring back glynnis talken campbell to voice her.
And to answer your question, no. Each branching story in WoL has a canonical path/ending that they went with for HotS. Siding with Tosh, siding with Hansen, and the nydus mission are the canon routes.
