When is the best time for a game to be announced?

Who cares if the people say the series is dead.
It's not like that hurt fallout 4 sales in the slightest.

On topic, it should be announced a around 6 months before.
A lot of publishers are transitioning to a shorter turnaround.including Ubisoft Bethesda and Nintendo.

Sony and Square Enix, and MS, have to step their game up on this matter.

There. Fixed that for ya. 

@ OP

Personally, I don't care, as long as the game comes out. Though, 4 years is definitely pushing it. I actually do like the 2-3 years thing, though, as I like following the progress of a game. Gets me more hyped for it. Of course, I'm not going to complain about it only being 1 year after the announcement.
