Just pray you get one of the Falcon models as a replacement. It should possibly reduce the chances of an RRoD compared to their old 2006 batch.

Dude I'm not a newbie here. A Jasper won't be provided as a replacement for his old core console. It would either be a old stock that they would replace it with or a fairly upgraded one, which would be Falcon. Plus we don't even have any sign of Jasper based boards out here in India. Most of the recent Arcade models have a manufacturing date of Dec 2008. So they could either be Jasper or Falcon models.The newest model is Jasper, Falcon is old.
