Xacex, I want a chance to prove you... er, hear your insights about why the 360 sucks. Please post them.
My personal current choice is the Xbox 360. I've had one since launch day, and have nothing but good to report about it. Xbox Live arcade rocks, voice chat rocks, and the coming updates are going to blow everyone away. Also, the fact that Xbox allows certain developers (including myself) access to data about the gamers on Xbox Live is extremely useful in creating applications for the Xbox community. I'm still excited to buy some of the upcoming accessories which will make the 360 pwn that much more.
But, I also plan on buying a Wii and a PS3, purely for the sake of not wanting to miss out on any of the next-gen games that attract me. Still, the PS3 is really going to be burning a hole in my pocket with its $600 price tag, so I'm expecting utterly awesome online services (of which E3 left nothing to be desired). The Wii, I wont be using for online play, purely because 'friend codes' are a shitty way to hook up with people I want to play with.
