This morning I was told that models are now gone on the Australian site, and when I checked, neither the US site or the UK site had any to speak of.
Of course missing models from the GW site don't really mean there is a release imminent, but it could mean something is on the horizon.
Please remember that epic returning is a rumor. I've included some rumors and link below regarding Epic.

Hey mate, just thought I'd let you know that the Oz web store no longer has
any models listed for epic Armageddon. Up until a day or two ago they had a
lot still for sale and now everything is gone. This May point to new
release at the end of year rumour or just be nothing,
