Shadow_Illuminus, surely you can see why people probrably aren't beating down the door to apply for your project: You are asking for highly skilled people, while providing very little information about what the project actually IS - just that it's "next-next generation," that it's going to be groundbreaking, and that you are looking to recruit people.
I can sort of understand your reluctance to give out information freely, because you probrably won't want people stealing your ideas, but you need to give information about the project if you want the most skilled people to join. For instance, people who like to program generally have preferences, and might be interested in certain technical challenges - some people might excel at AI programming but would not be interested in coding a renderer. Some people, on the other hand, might like coding a renderer, as long as they don't have to write any complex math operators. Similarly for art, most people have a certain graphical style, and if they don't know what your game is aiming at, they don't know whether they'll even be suitable. For instance, some people are good at drawing organic shapes but not machines. Some people can draw realistic figures but can't do "cartoony" characters without making them look funny, etc.
Concern over idea stealing is common, but irrational - simply because with the exception of perhaps an exceptional story idea, etc. ideas are almost always accessible. New features in games, etc. have generally already been covered extensively by Comp. Sci. thesis papers and seminars long before they make it into games - really, there's been very little innovation from a conceptual standpoint in a long time, but it's more an issue of finally having the computing power to implement a certain idea that people started writing papers on decades ago.
