Exciting news: over at the TOS forums, Sue Rostoni states the following:
"We've signed Paul Kemp up for a duology -- I don't have any other information I can reveal at this time. We're not sure of the pub dates yet....nor the format (hardcover or paperback)... so no questions as I have no answers."
The first Star Wars book from Paul Kemp was Crosscurrent (paperback, January 26, 2010). The author is currently writing the Crosscurrent sequel Riptide (paperback, July 26, 2011) and his novel The Old Republic: Deceived will be published on March 22, 2011 (hardcover). So the earliest publication-date for these new books will probably be 2012...
