I think we're pretty much all expecting an east coast start, heading to Europe first, possibly Latin America.
We are? That's news to me. It might be right, but I haven't heard any reasons why it will happen.
News to me too.
"Pretty much expecting" is a too strong of an expression. Hope should be a better way to take it.
Production wise it would be easier for producers to just repeat LA as start city once again. I sense a lot of fans are hoping (maybe expecing) a change for TAR20, after so many cycles starting in LA, maybe TAR20 will start in the East Coast.
Personally I speculate LA again if they keep with the West Coast start city, as someone pointed elsewhere, the staff there must already be used to it.
However, if a East Coast city is to happen, NYC seems to be a possible location for the start city, as would fit well, with NYC being the end city for TAR1.
