the 300$ package comes with a wired controller and standard av cables
the 400$ package comes with a wireless controller, a live headset, a 20gb hd, component av cables, a silver live membership and for a limited time a remote controller for the media center
Damn you microsoft, what's the deal with a wired controller with the core system? The xbox360 will be the only new gen system to ship without wireless controllers, unless you want to dish out an extra 100$. MONEY!
Oh and if you're thinking there's a base to recharge the wireless controller, think again, you have to buy it seperatly.
