It's nearly completed and is expected to be submitted at the end of April/Early May.

RobTop says he started working on 2.1 in late September, then suddenly he said he wasn't satisfied with the result in January, and he started working on 2.1 again.

Technically, this means that RobTop restarted the development time. For a big update like 2.0, the development time is 9 months. For common updates like Update 1.9, I believe it takes about 3-4 months to make an update.

When RobTop restarted the development time for 2.1, it's probably gonna take about 4 months to finish, like 1.9. HOWEVER, the actual development time of 2.1 was 8-9 months, just like 2.0, because he started working on the update in late September (when he posted the first teaser image with the spider)

I would say it's most likely about to be finished. One of RobTop's mentions, tweeted by GuitarHeroStyles, said that adding a new setting/option would be a bit dangerous, as I bet it would cause crashes.

Not only Apple, but Steam, Google Play, and of course, Windows 10 Mobile/Windows Phone.
