We've never said either way if Third Person support will be included in the future, because it hasn't yet been decided. Consequently anything posted here so far is pure speculation, and should be treated as nothing more. The engine has not ruled this feature out, so there's no reason for anyone else to unless stated otherwise.
The name of the product is irrelevant. It doesn't matter if you have third person camera locations in an FPS game (Max Payne, Halo, etc), they're still classed as an FPS. The term "FPS" relates to a genre, not a technical feature, and should be treated as such.
If you think about it for a moment, there isn't actually any such genre as "third person game", probably because it doesn't actually
mean anything.
A great many people think they are thinking when they are really rearranging their prejudices.
