Today's PSN update will see the release of a $5 expansion pack for echochrome on PSP. The PlayStation Blog states that the PSN's mind-bending puzzler will receive an additional 40 stages for the doll to survive.
The expansion pack will also be offered in a bundle with the original game, though no price was set. There is also no mention of an expansion for the PS3 version, which released the same day as the PSP version back in May.
