What’s happened to the early WW2 “Attack Force” multi-tank boxes?

Hi,

I noticed that some of these boxes no longer appear in the Warlord/Bolt Action catalogue – specifically the early war “mixes” – eg Somua + Renault: Panzer II + Panzer IV; or the British Vickers + Cruiser.  Does anyone know if this removal is permanent?  I have to say, I found these boxes excellent value and will miss them if they are gone for good.  Alternatively, can anyone at Warlord comment on whether they are being replaced with other mixes or new combinations (which would be good!)?

Thanks,

BM
