Ask HN: Why does everyone call it Sublime Text 2

I guess it because nobody know about Sublime Text 1 as popular application - Sublime Text 2 it's like the first known name of this app.

And I believe that the new version "Sublime Text 3" will be called as "Sublime Text" by everybody (or might be "Sublime Text 2" version 3 :) )

The titlebar of the program says Sublime Text 2

Why does this question even exist?
