MDGs to be re-written?

Rumour has it (BBC TV Newsnight) that a commission chaired by UK and Brazil is to lead efforts to re-write the Millennium Development Goals. What good news, and about time some of us would say. I guess that because forgetting about them altogether (good option) or admitting that the idea of such goals was wrong (better option) would be politically impossible, re-writing them so that we avoid a day of reckoning is the only viable option?
