It was rumored that since Lex is gone, The writers have made their own version of Doomsday in the form of Davis Bloome.
Here's a snippet of what they said:

Davis will actually be Smallville's interpretation of Doomsday, the only character to have succeeded at killing Superman. In Smallville, Doomsday will be represented by a "nice guy" paramedic, who grew up moving from foster home to foster home. His storyline will be very dark in that the character will uncover horrible truths about himself. Witwer explained that over the course of the season, his character will come to resemble that of the comic book counterpart he is based on. Brian Peterson explained that the new executive producers were looking for a villainous character that was "as great as Lex", with Michael Rosenbaum's departure, and Doomsday fit what they were looking for.

Now I have said DD would kick a** on Smallville, and this seems a little cool. I would like to see Clark verse Doomsday without the whole dying thing. Any thoughts?

P.S sorry I havn't postd i n a while. I've been reading the Twilight series. 4laugh
