I read a couple months back that Sony and Sandisk were working on a new form of memory stick, dubbed 'Memory Stick Pro HG', which has capacities upwards of 32GB. However, the PSP will probably not be compatible with that.
Supposedly psp can support only 32gb. There is a group working on putting in a 30gb ipod hd in the psp using the umd connection.
I have four 4gb sticks, its tedious to put them in and the capacity isn't great for the amount of games i want in it. I'll probably wait for a 16 or 32 gb stick. New hg sticks will be compatible but won't have the same speed unless used in a actual hg reader.
