Moncton or SJ do seem to be the most likely; both cities have industrial manufacturing.
Freddy has always been more 'soft' engineering (as in software) and doesn't really have the industrial base that would attract this sort of project, so it would be a long shot for it to be coming here.
Still, a good project for the province at large.
*Edit* I hadn't noticed it was a project for "Southern NB". Moncton is by far the most likely target then, followed by SJ. Freddy is classically "Central NB" so that would take it out anyways.
