Apple has put up a teaser page for tomorrow’s big announcement, and some speculate that the service could “be moving to a cloud-based iTunes where users’ music would be stored on Apple’s servers and streamed to a variety of Internet-connected devices.” We’ll keep you posted once/if more information is released.

Apple has also been rumored to be working on a subscription-based music service that would complement the existing pay-per-download service.
