I understand the problem, but so much the worse for them, if I pay, I want something I like, and at least decent longevity is a game's indefeasible requirement for my tastes. And luckily I'm not alone.
Anyhow the problem is more for single player games, good multiplayer games are intrinsically long-lived, SW houses must live with it or give up and develop something else. A short-lived multiplayer game will gather a scarce and unenthusiastic community, killing itself very soon. They can try dirty tricks with renownned series once, at most twice, then reputation sinks and short-term and short-sighted greed will kill dishonest SW houses.
