La notizia è trapelata da una mail inviata dalla Sony stessa ad un manager di uno dei tanti Eb Games.
Ecco la fonte della news:

This is information I recieved from my EB Games Regional Manager source in:

Sony was sending out Emails to its Commercial Retailers that all new PSPs to be sent out will have 'Downgradable Prevention' built right into them. All new PSPs to be shipped out as of next week Friday, May 18th, will be a higher firmware, 4.xx (specifics were not released), but they were promised to include new security features to prevent hacks and downgrades. Apparently this is one of their first steps to start focusing on the PSP again, instead of diverting all attention to the PS3.
The new firmware will be available for download off Official, and most likely Unofficial, sites 2 days after the shipment is sent out.
This also happens to be the shipment of PSPs to be sold for the price of $169.99CAD with a Game. As of now, you can still purchase the downgradable PSPs for anywhere between $190.00-$220.00 depending on the Commercial retailer.

This news is obviously coming from a Canadian EB Games, based in Calgary, so this might not be effective for those in Europe, but possibly for the USA. These shipments are expected to be North American wide.

Per coloro che non masticano l'inglese, in questa mail viene detto che durante la settimana prossima (intorno al 18 Maggio) verranno spedite ai maggiori rivenditori del Canada e probabilmente anche degli USA, PSP montanti un nuovo firmware "4.xx", con nuove protezioni che teoricamente dovrebbero prevenire qualsiasi atto di hacking al fine di downgrade.

Non ci resta che aspettare il prossimo venerdì per sapere cosa ha davvero in mente Mamma Sony :rolleyes:
