What? Look at the lower left corner of DA* 55mm, you can see that the DoF is shallow and bent, but it still renders detail even in extreme corners (the little square cup; the little branch).
The DA 40mm shot is a bit too dark (with lots of noise and apparent sharpening in PP), but it still seems that the general structure of branches, wall is fairly good even in extreme edges.
Anyway, Pentax Forums will be conducting tests of
a lot of lenses on the K-1, so you can just sit tight and wait for the more reliable results, form PF staff, various bloggers, and other users.
