Well... If I correctly understood, EON wants Mendes to be back for Bond 24 and producers are ready to wait that he finished his theater projects and start pre-production of Bond 24. But in this case, we have to wait 2015 or 2016 to see the next Bond movie.
I don't find this is the best decision. I prefer to see another director for Bond 24 and why not Mendes for the next after.
I'm with you on this: I don't need another 'masterpiece', just a darn good action thriller. And I'd like to see it much sooner rather than later.
