1. Sublime Text 2 (and also Textmate 1.5) are STILL good editors. And they will continue to be good editors for the foreseeable future. Just like Vim and Emacs. You don't need a newer version every year. Even though Vim and Emacs DO release newer versions, I have no idea what is in the new releases. Why? Because Emacs 22 and Vim 6.3 do well enough. Textmate 1.5 does well enough. Sublime Text 2 does just fine.
2. I get the bus factor ideal, but it doesn't always turn out that way. Sure it's a chance, but look at the Jack Slocum, ExtJS situation. He was a one man show. He was a machine that could output beautiful amazing work. Then he actually let Sench Labs take over. He seemed to disappear for a time. They had a few stumbles. Now he's back. Same could happen. The same could happen for Sublime.
Overall. I don't see it as a hinderance. Watch Railscasts or Peepcode. They don't seem to have a problem using a 5 year old editor. Heck, I still use a table saw from 1982.
Actually, Emacs 24 was quite an important release that improved many things. For example, it introduced an integrated package control and lexical binding.
