Few games nowadays can boast of having multiple endings.
If you narrow the field the last couple of years, with respect, this becomes a self-fulfilling statement, since very few RPGs are being released. How many years will you allow for comparison's sake?
Actually multi-endings is not always found in RPGs. Jedi Academy had a customizable avatar and an RPG-ish skill system yet it was an action game.
But to re-state your argument, I'd say that very few PC games are being released, comparing to the console game-flood.
