No. This simply isn't true, Sublime Text 2 has one of the least complete examples of a "vi-mode" I have used. ViEMU, Emac's EVIL, XVim for Xcode, all seem much better thought out and break less muscle memory than Sublime Text 2's vi-bindings. Sublime Text 2 left out all of Ex... seriously.

The only major upside is that Sublime Text might have a 3rd party step in and fix its broken vi handling (someone started to do this with VintageEx).
