6 moths of support for current apps, after which they are no longer officially supported & future upgrades to the OS may break the backwards compatibility. You have to keep in mind the reason they are not supporting it at all is to prevent folks from using "ugly" legacy applications, not because it is too much effort to add the support.

MS is trying to re-image it's product. Supporting older apps will hinder that on the marketing side...Because why would developers invest in a new application development if the only thing they were building for would be eye candy.
