I'm not reading much into it. The statement basically lumps RDR in with Bully and L.A. Noire as games that "sure, we *might* make a sequel someday - anything's possible."

It was three and a half years between the release of GTA IV and the announcement of GTA V. Considering that a new RDR would likely require the same level of development, sadly I wouldn't expect to see any official announcement before late 2013.
