It won't fail, nor will it die, honestly. - What you need to consider is this game has a very, very loyal fanbase. I don't think it'll go on healthily for the next decade, but I do think 3-5 years the game will still be OK.

It's not the greatest it has ever been, but I would say it isn't the worst it has been either.

Provided they don't do the same as EW, where they are at a replay deficit then it will be OK, and I think given they are looking at a 'new form' of combat content in addition to exploratory content, then I think there's not really much to worry about.

For those who have been playing a long time, the games formula has also been very apparent for around the last half a decade.
