If any company wanted to scale back, why would they scale back Halo, a series where the latest instalment is easily going to cross 10 million sales?
By the way, if there are hundreds of Puzzle Quest games (I don't see why there would be, look at its sales), only a few will do well, the rest will flop. Then somebody will make a hardcore game, it will sell extremely well just because there are no hardcore games out that year, then developers see how well it sells and go back to making hardcore games.
So, no.
