The Sigma DP series concentrate on two subject types; limited portraits and limited landscapes. Sure there will always be the megapixel debate for that type of sensor. But for those two subject types the Sigma is considerably better than any non full frame up to about the 15mp range. And yes even though the lens is not interchangeable any of the DP models offer an optcally incredible lens. Even most slr lens cannot match the DP lens.
So unless you really happen to speacilize in portraits; I would not recommend any of the DP's.
Some of the samples on these pages look quite stunning:

But as you said the use is very restrictive, even if the DP1 will have a 28mm equivalent so maybe usable for a wider variety of subjects.
@RonHendriks1966: Yes I got the silver K-01 with the DA 40 2.8 XS for 399€.
They told me that they still had copies in some of their stores, so if you want to grab another one it's still time
