does microsoft or sony have a "mario killer" in the works?

It's usually the main problem in this industry: when a game has some success, we see waves and waves of copycats, usually never as good as the original...

Plus, if it was so easy to match Nintendo's efforts, how do we explain that after all these years, no one yet has brought that so-called "Mario killer" in the platforming genre?

Same thing with Zelda: a "Zelda-killer"? Where? Tell me, i'd really like to play other games in that vein... but i never found a single one, with the possible exception of Okami...

Same thing with racing: in the arcade/cartoony racing style, where are those "Mario Kart killers"?

Same thing with fighters: who has "killed" Super Smash Bros?

I'd say it's easy to criticize, but when it comes to game's quality and game's success, Nintendo is definitely a very hard contender...
