So is M33 developing a CFW...

for the slim PSP that will have the same functions and abilities as the Fat PSP CFW now that can run almost all of the homebrews. (if possible) I want all the features the fat PSP has to offer on a slim&lite PSP. Is there a project on this and can I expect it in the future?

You can expect the programmers to update there programs to work on the slim.. But no, you can't expect 1.50 homebrew on the slim.
