As you might have already seen, there are some mobos (TA-088 ones, slim models) in where the IPL used for Despertar del Cementerio, Pandora and Time Machine therefore, doesn't work.
IPL can be still run from the Memory Stick, but just those that are signed by Sony, and not the ones that contain a different signature; a problem that will probably block the actual way of running your cfw's, as you couldn't even load on this NANDs the custom IPLs with different signature.
Even though, IPL is not the problem, but probably the mixed kernel of 1.50&&3.40, and it will be the best option to use a new kernel on Despertar del Cementerio future versions.
So, to sum up, new Dc version will not be released till the new Core and interface is finished.

So I think we will be seeing a sudden rush in psp sales before the new TA-088 comes out . If you have been putting off buying a psp NOW IS THE TIME .
