Not strictly - whilst it may be more difficult to download TS2009/TS2010 assets from the Download Station into TS2009/TS2010, and no new TS2009/TS2010 assets will be able to be uploaded to the Download Station after next Monday, it should still be possible to download from third-party sites without any issues. In terms of downloading using Content Manager though, TS12 users will still be able to download without needing a First Class Ticket.
