When Microsoft starts selling the next Xbox, what do you think they'll do with the 360's achievements?
1.) Start from scratch, 360 achievements will not transfer. If your gamerscore was 20,000 on the 360, you'll start with 0 on the next MS console.
2.) 360 achievements will transfer and the next XBOX will continue using the same achievements the 360 uses. If your gamerscore was 20,000 on the 360, you'll start with 20,000 on the next MS console.
3.) 360 achievements will transfer but there will be 2 categories of achievements (one for legacy 360 achievements, and one for the new XBOX achievements. If your gamerscore was 20,000 on the 360, you'll keep that 20,000 gamerscore in your 360 section of achievements, and you'll start with a 0 gamerscore on the new console's achievements.
I'm thinking they'll go with #3. I think they'll do something to freshen up the achievements and make them more interesting. But by doing so, they can't continue with the current achievement model they're using with the 360. So we'll get new achievements and a new gamerscore to start with the next box... but we'll have our old 360 achievements visible by us and friends. This way, you could pickup older 360 games on the next box and still get the achievements for them.
