As posted on Gizmodo today, Microsoft will be making development on the XBox 360 available to just-about-anyone for a small subscription fee, as well as being able to play other homebrew developers' creations.
This is in stark contrast to Sony who since the inception of it's ill fated PSP has done everything possible to stifle homebrew development in the name of defending against piracy. Ironically, considering it has failed as a movie and portable media player and is falling ever further behind the Nintendo DS in games, perhaps Sony's destroying the last market interested in the PSP.
When consoles have existed solely ON the basis of homebrew development (the GP32 and it's successor) and have done moderately well with only a fraction of Sony's marketing muscle, it's a wonder if Sony is simply being paranoid about piracy, and denying one of the most original and creative sources of software and game development?
