Probably not. According to Yoshida to his live letter from 2.1-2.2, he did mention that there are a lot of contents and needs to catch up from 1.0 lores and etc that they've missed due to fixing it into 2.0 ARR contents.
So the new patches will keep happening until Yoshi-P retires or resigns with Square Enix. His contract for Final Fantasy XIV project has been going on for about two years since 2011-2012, and his decision to stay or leave will be by 2016. (That's when most developers/producers leave after 4 year agreement term)
But also, FFXIV isn't throwing the entire content in one big patch like Tera/ArcheAge. There seems to be always newer part of story into the game. They probably estimated that regular casual players would beat the story mode within 2-3 months at least (By doing one or two quest per day at least along with some side quests and grinding. Casual players only play about one to three hours per day. - Heck not everyone plays during weekdays and play on weekends and yet they pay $12-15 per month because they enjoy it.). Which means that all of the story modes that we've had from 2.0-2.5 were actually just A Realm Reborn "expansion" itself with unique arc titles.
I have a feeling that it'll slow down by 4.0-5.0 expansion but 3.0? I think Yoshida still has more stuff in his pockets to show every 3 months.
