Hopefully MS/Bungie learn from Infinity Ward - Advertise your map pack on TV! :P
I mean, months later they can still sustain growth because the name is out there and they are pushing new content. With Reach they should do the same - release map packs a few months later and keep it fresh. I'm not exactly for $15 map packs (I ended up buying them anyways) but with enough advertisement people will buy em.
It's just that simple.
