Should I buy a PS3 this holiday?

For the Spanish speakers (readers): ¿Debo adquirir una consola PS3 estas Navidades?

I have both a Wii and the Xbox360.  I love both because of the diversity of games and extra functionality.  Love RPG (Japanese and western).  Love "casual" games like Animal Crossing / Harvest Moon (!!!! my wife plays it and I catch the “virus”) and love "hardcore" games like Halo / Bioshock / Wii Kart (yes, WiiKart is hardcore).  Also love the streaming capabilities of the Xbox360 and the Live online service.

Does the PS3 will offer me other/better gaming experience or is better for me to save the intended purchase money towards other Wii60 games like Fallout / Gears 2 / Wii Music? 

Please excuse my English.  My maternal language and the one that I use in my Work / friends / family / University is Spanish for about 90% of the time. 

Please comment.
