I agree with Sindran. I would like to have the choice.
I have 2 accounts, with 1 BF sim on each. I would have liked the opportunity to visit other cities too, like AV or DC where I used to have sims before. Since my TC3 sims are now filling up the rest of those 3 slots, there is no way I can do that. It doesn't really matter to me how many new slots I will have the day EALand opens. If I only have 1, fine.
What I found the most annoying, there was no information to be found about this. Had I known, I would have created in the production cities of my choice first, then in TC3. I would love to see these 2 select sim pages separated. Like it is now, I'm basically stuck in either BF or TC3.
To get information about how the game is now, you have to look through a lot of posts here at the boards (and be lucky you get any relevant threads when you search), at the blog, EA's customer support pages (some information there is not correct) and the official TSO site. Not everyone has the time, or the patience, to look around. I am not surprised new players are confused, even 'old' returning players.
