I think we're all aware of that, but that doesn't mean we can't try and influence their focus.
It's always been stated they'd work on the "most popular" titles first, which is probably based on sales figures.
MM3 was bundled with the Xbox console for ages in a number of packs which in my mind means there's a lot of people out there with it, but it might not show up on their sales stats as "popular".
I've also read / heard in a blog cast that the back compat work is not done by a dedicated team, it's a lower ranking task owned by a team that no doubt have other priorites.
