Just cutting down on the number of Codices, and writing the all-inclusive Space Marines Codex general enough with a wide enough variety of options that all models currently in existence can reasonably fit in there somewhere. I, uh, didn't suggest making any models OOP.
With all the newly added armies, the ones basically already announced, and a few rumored to be coming, shrinking their 40k product line, does not seem to be the path they are on. If GW has proven anything over the past year or so, is that it's not looking to shrink it's product line for 40k.
