Eh no.
While it's too hard to say, Fire Emblem as a series seems to have one team working on each title. Why does this matter?
Well, there's definitely a likelyhood that the next title will be a sequel to FEDS that's either FE3, FE3:Book 2, or a brand new title. There's little chance of it jumping to the console ship because of production cost, speed of production, and simply remaining consistent.
Then there's the potential for a remake of FE4, which like the remake of FE1, is more likely to be on the DS. Granted, it's almost entirely based on the speed and cost of producing on the DS compared to the Wii. In spite of little need to actually give it an english release outside of it's unavailability in english, it's widely considered one of the better titles. The remake train of FE1 and potentially FE3 grants a decent chance that by FE15, there will be a remake of this title.
The remaining chance at a new title still has a better chance on being on the DS. It'd be different if I thought or it seemed like IS had 2 teams working on 2 FEs. Then I'd also bet on a Wii FE coming first. But the titles come out too far apart for that to be a likely truth.
As for the topic, no. NoA has gained some weird habits in spreading out game titles with odd dates simply to gain more money.
