When the Wii and PS3 first launch.  Wii had a major title (LoZ Twilight Princess) and followed by two games closely followed by most hardcore gamers which were Super Mario Galaxy and SSBB.  After SSBB the Wii's game quality just went down hill and its just casual game after casual game with also a over-saturation of shovelware, and we all know what happens to a console with a over-saturation of shovelware *cough* Atari *cough*.  Yeah Wii has its sales but thats about it.  Online multiplayer is horrible, Holiday lineup is a joke, Nintendo seems to not care about core gamers anymore, and most of us core gamers just use Wii as a emulation (Virtual Console games) console.

PS3 on the other hand did the exact opposite.  It went from having hardly any games to having a bunch of quality with a bunch of killer apps.  With the Wii only have Animal Crossing in its holiday lineup.  PS3 has LittleBigPlanet, Resistance 2, and even MotorStorm Pacific Rift.  Along with MGS4 from June.  Their online setup is really improving and their online store is really getting a lot of content.  The sales are even improving even if their not at Wii level but really how could you.  The only way that could happen if Sony sold out (I'm looking at you Nintendo). 


So all in all Wii has sales.  PS3 has everything else.  PS3 is a good alternative to 360 but Wii.....I haven't touched mine in since Wario Land Shake it (September) while I play my 360 and PS3 almost every day.
