Here is a tiny rumor bit hinting at a new land speeder type that will make the new Dark Angels codex. I dont know if it is the same as the new flyer we are supposed to see, or something completely new.
This bit is from the question about if there are going to be any new units in the codex. So while vague and brief, it is at least something for a late Sunday afternoon.
Please remember that this is a rumor.

You can certainly expect a new speeder type
