Many thanks monkeybeartso and DutchAmerica for answering my questions.
From what I perceive from DutchAmerica's very nice link to the Q&A it seems like TC & TC3 & Betaville will only be merged together and will NOT be part of EA Land? here is the direct quote from the Q&A link below.
What is EA Land and what does it mean to me?
EA Land is the name given to the consolidation of all current cities (Aside from TC and TC3) and Betaville.
AV, BF, FF, IH etc will all be merged into one main city – EA Land
This means that each city will be picked up, given the new code and placed on a larger map, that is currently seen in City View, and connected to all other cities, even the ones not yet in use. EA Land will look something like this . (Please note this is not the actual image of EA Land, this is a mock-up of how it may look).
If this is true than from what I gather here is that TC, TC3, & Betaville will NOT be part of EA land, So why is everyone wanting to be on TC3 & not playing on any EA Land cities?
