-[Every week, Gamasutra sister weblog GamerBytes' editor Ryan Langley will be summing up the top console digital download news tidbits from the past 7 days, including brand new game announcements and scoops through the world of Xbox Live Arcade, PlayStation Network and WiiWare.]

While there has been plenty of news this week for the Xbox Live Arcade, including the release of Castle Crashers this Wednesday, there has been significant new information on PlayStation Network games from the Leipzig Game Convention too.

Sony released a stack of new trailers available for download on the PlayStation Store - reminding us of notable titles like Wipeout HD, Fat Princess and Flower - but has also announced Savage Moon, a new Desktop Tower Defense style game which I'm sure will tickle the fancy of many PS3 owners waiting for more PixelJunk Monsters-like content.

GTI Club+ was also announced for the PlayStation Network - I hear Gamasutra publisher Simon Carless is a huge fan of the original arcade cabinet version. It looks like it's in good hands over at Outrun 2 converter and Foundation9 studio Sumo Digital.

Finally, don't forget that Ratchet & Clank: Quest For Booty was released last week for PSN, and Helix has just debuted for WiiWare, as well.

Here's the rundown of the top console digital download news for the week:
