To Wii or not to Wii.

I've been postponing my PS1 upgrade for a couple of years now. I had my sights set on the Xbox 360 for the hi-def resolution but, after experiencing the rush of adrenalin, laying punch after punch, bobbing and weaving and knocking my opponent ruthlessly to the mat in a bout of Wii Boxing, I'm seriously reconsidering. It boasts a controller that serves as an extension of my body, forcing me to use muscles that have been in hibernation since the early 90s. The picture quality and game detail is definitely sub-par compared to the Xbox, but the physical interaction brings a whole new dimension to gaming. I just can't decide between the two. Pros and cons anyone? — Mick, Designer
