Wizards don't comment on unanouced products. As such, Mearls gave the only possible answer. He stated he doesn't players to be surprised by the direction D&D is taken.
Right now, I belive he is creating a concept, I wouldn't expect a product in less than two years. Also, they might try something different than a new edition, more similar to the Essentials line. As currently the errata is huge, they might opt to revise the core books. What Mearls is describing is a simplified version of D&D to accomodate game styles not currently supported by 4th ed. However, he could desogn this system within the current rules and add this information in the revised core books. As fourth edition seems to be strugling in sales, a relaunch could be a possibility.
