I believe Kate Ryan and Bobina are coming out with albums this year too.  Tiesto will also release an album of Remixes from his "Elements of Life" album as well as a new DVD.  Ferry Corsten and Infected Mushroom have both stated that they have new DVDs in the works.  And last but not least, Ultra Dance 09 will be released this week

sweeet

I can't wait for Sander Van Doorn's album to hit.

Personally, I can't wait to hear what Astral Projection will come up with this time. Love those guys.

im looking froward to hear Agnelli & Nelson, Armin Van Buuren, Ferry Costen, Dj Tiesto, Jes and Juno Reactor new release this year.

I'm really looking forward to the Armin, Cape Town and Ferry artist albums!
