Kickstarter.com is a nice fresh idea: You present a project, define what it will be, show some concept art, sketches or a video of somebody explaining it, and you define pledges and associated rewards. A simple pledge can be a copy of the new RPG book, or a copy plus t-shirt, or even being included in the book as a NPC!
Then you get funds directly from buyers, and they get their pledge when you finish. Is amazingly simply yet brilliant, and what I love most is t hat you no longer need middle-companies or distributors, so you get mor profit and less restrictions.
While there are some really cool projects about physical RPGs, custom dice or new expansions/modules for existing games, two computer RPGs have all my attention (and now a bit of my money ;)
I'm pretty sure more cool games will appear, but this two ones are looking really promising.
Bonus: Legend of Grimrock has just been released a few days ago. The game is a tribute to the legendary Dungeon Master, and from a few hours of play I can say it's recommend for all old school CRPG lovers.
