I have to agree here, people are going to love this. M$ really know how to make their product a hit and this will only make it even hotter. There are plenty of people out there with coding experience who through the use of XNA will be able to make their own games and share it with others in the X360 community. Personally I think its also a great way for them to get known as there is a huge "homebrew" community that sorrounded the XBOX and I think naturally will move onto the X360.
