They still might keep their original plan, working with smaller teams for longer periods of time but just adding more teams so they can release a game or two pretty much every year. Not really sure how many states/countries/cities offer up as lucrative tax cuts as Montreal/Quebec, but I would imagine that's a big factor when you are expanding the company. If you look at their Q&A team, you can see it's pretty big already. Square might just as well focus more/most of their internal Q&A to the Montreal locale due to the tax cuts.
