Well, WipeoutHD is basically a HD version with Wipeout Pure and Pulse assets. It's a niche genre and well known as a game with very high learning curve. 140k is pretty decent based on those facts, but WipeoutHD sales WOULD be more if it weren't for all the game trading that goes on PSN these days... so in theory, it's probably even less than 140k....
Hopefully, it'll have good legs. For $20, this is the most valuable game on PSN.
