Well, the NA PSN store just recently came out (or is coming out ... I lost my dates) with the digital version of NA Demon's Souls, for $20. The EU PSN store is following suit, and will offer the digital version of Demon's Souls as well come January 23rd. This is, indeed, good news since the EU version is very difficult to find and when we can find a copy it's extremely expensive, particularly for those of us in North America. This is definitely good news the way I see it!
