There are some polls on future polymath projects here.

Here is a link to a post on a possible polymath project. It is Erdős’s discrepancy problem.
Polymath3 now has a tentative starting date. It is April 2010. There is a post giving the details here.
Here is a post on derandomization. It includes material on the problem of finding a deterministic algorithm for finding primes. It also has a section on the construction of Ramsey graphs. There has recently been an improvement in this area although there is still a gap between constructed graphs and the random graphs.
