Well to be honest I've paid for WAW maps twice once in WAW and once in Blops 1. I don't really feel like paying a third time for WAW maps and a second time for Blops 1 mathey now if they were free if you already purchased them then that would be different. Could you imagine how much they would charge because of the high demand for them?
With the strict no dlc past october first rule, ps3 is month later so 100% confirmed wont happen
if your that deseprate put you blops1 disc in, most maps you can find players except maybe shangri la.
but tbh no one will play blops1 maps on blops2 much with gta5, cod ghosts, next gen... Who would play maps which are 2 years old? it would be a waste of time and effort, hence the reason they didnt re master them.
