There are rumors still of models that have been seen, that are not here yet. It's of course thought that these will be up for pre-order next week along with the Ork codex.
That is the date is speculated would put these up for pre-order on June 21st, with a release date of June 28th.
Please consider these rumors until we get an official announcement.

From what I know, still to come:
Big Mek in mega armour with kombi shoota and vice like PK sort of thing and KFF on his back. KFF smaller than current Big Mek model's KFF.
Big Mek in Mega Armour with shoulder mounted beam weapons, KMB and vice like claw
Those two could even be the same kit?
Meganobs, including those with two buzz saws (Presumably the kill saws Beasts of War mentioned)
Remodelled AOBR style Warboss, with kombi shoota, PK with a circular saw thumb, and a large attack squig in the same base (Could be a seperate model)
Painboy/Mad Dok with some form of cybork klaw hand, syringes/bscalpels for fingers, grot orderly on his back.
