Man, that really, really sucks, I guess I picked a lousy moment to get a 360.
You dont suppose there could be a way to simply patch the games once the new dashboard/ap25 checks are implemented to remove them and make them playable on previously flashed consoles do you? Having to find a new way of burning, staying offline(though normal updates/fixes for games could be needed), needing to reflash (though this could be expensive if one doesnt know how to do it himself) are not that bad, but losing all your back ups? Thats just criminal, particularly if as someone on that threat you linked to mentioned ms starts doing this on a regular basis
I really dont want to go and waste all the dvds Id use burning games now if I have to reburn later, but then I only have like five games and someone said the new dash might not come out until november, so yeah, I dont think I could just wait that long without burning anything.
*sigh* And here I was hoping this would be a late april fools joke.
