There's pointless Archives 59's too... also Streets 00 158 but this one is a bit further to go.
I'm tempted to say that the popularity growth of GE on the shorter term will mostly depend on Goose and Cosmo (and possibly another partnered streamer if s/he can grow really fast). Many new players emerged and some of them will quit (or lose interest/huge breaks), but, say, next year, if the game doesnt stagnate (I hardly doubt it), there will be even more new people than there was on 2014 total, and the former newbies will start to go for the harder stages (in a common sense...).
The higher tier world records may never be tied by tons of players, but eventually things like: S1 102, Depot 25 and Cradle 34 being tied by more and more people; a few guys tying the more difficult times etc will happen. It's unlikely that new players are going to come and crush it with less than a year, but today, with twitch, tutorials, more people to form peer groups, multiple PR/WR videos and direct computer capture (if you wanna analyze yours and the top player's gameplay, make comparisons) etc, the default will be to get good faster and faster, not like when the community was smaller, everyone was on dial up and you barely had a few people camcording/taping there gameplay.
Goldeneye 20XX, boys. No gaming community can escape it.
