MS has announced far better support for indie devs, including self-publishing:

Self-publishing is also coming to the 360 at last:

What this all means is that indie devs will no longer have to spend $$$$ having a proper publisher to be able to get their games on the XBLA.
I also read something related to this about MS improving the certification process for XBLA games.
