Hmm. Despite my better judgement, that does pique my curiosity. Mostly because Ray's impatience with his Midkemian epic was palpable reading the last three sagas of the Riftwar Cycle. I get the feeling he felt like he'd messed it up and wanted to keep starting anew with new reincarnations of old characters, but then couldn't muster the effort. This new series could be his fresh start, and maybe it'll show in the writing. That said, I'm pretty sure my estimation of his literary talents is irreparably damaged. I'll be surprised if it's actually any good.
Also, I'm baffled by the whole 'show tunes' thing ... I guess he's joking?
