Same, I find it very difficult to believe that SW won't get a new/updated primaris character. Those Orks vs SW boxset rumour have persisted for so long and with a new Ghaz and several orky looking rumour engines it wouldn't surprise me if it all materialises in March. Of course, the SW side of that box might be a bit sad in comparison then with only a new character being the new sculpt on their side. However, Ghaz is probably not going in the box either IMO due to him becoming the flagship ork product and we know that the primarchs sell exceptionally well.
But a new KFF mek, accompanied with skarboy/'ardboy models (that RE boot) and potentially kommandos (RE binoculars) and/or something that hasn't even been teased versus new SW char and random primaris stuff doesn't seem all that crazy to me. PA6 is probably a two-weeker IMO since Ghaz will have his own release slot and not swamped in with all the new PA rules I'd imagine.
