Linden Lab is going to roll out a replacement for XStreetSL this summer. Merchants can get-by doing nothing. Transfers to the new system will be automatic. You can read about what is coming, the timing, and see screen shots of the new system via links from Pink Linden’s blog post: Announcing the Second Life Marketplace Beta
This update will tie SL Market Place and Second Life more closely and make transferring funds between the two much easier.
