I gotta figure this means they'll have to carry on the current platform for at least 2 more years, probably 3, in order to justify the cost and effort to move all the tooling and build a production line in Canton.
Because otherwise if they've already got the 3rd-gen model in the wings for 2014, they're going to have to either halt production for a while to re-tool the new Canton line for it, or they're going to have the 3rd-gen line and tooling being built-up while the 2nd-gen line is winding down, which will require more space in the facility and higher demand on their other facilities and supply chain.
