Looks like some big news is coming for the PSP Scene, as it has apparently been CONFIRMED that DarK_AleX and then gang indeed are working on a v2.71 downgrader. Here is the lowdown, according to MaxConsole:

"We can now exclusively confirm that a PSP v2.71 downgrader is in progress. The usual suspects are hard at work in such as Dark_Alex and Yoshi, it\’s currently being tested with a Undiluted Platinum modded (unbrickable) PSP to ensure it wont harm anyone\’s shiny little handheld when it\’s released. The downgrader is expected to be released very soon after some more extensive testing."

I guess all there is left to do is wait. Be sure to keep checking back to PSPBrew.com, as we will be sure to be giving the latest information on this huge development.
