PlayStation 3 Getting 4.20 Update Tomorrow [Update]

[Update] PlayStation Blog has made it official.

[Original Story] According to a post on NeoGAF, a PlayStation 3 firmware update is incoming on June 26th. Going by the past 50 or so firmware updates, this will A) do very little to upgrade the PS3, and B) release around midnight EST (tonight).

How this sneaky bloke knows what Sony has planned is anyone's guess, but mysteriously, the changelog looks strikingly similar to what Sony puts out themselves shortly before the firmware is set to go live.

The changelog proves theory A:

PS3 System Software version 4.20 will be released on June 26 2012. This update will introduce a number of new features including:
