Not really a rumour and not so much news, but not sure where else to put it. Saw someoen mention this on DakkaDakka and checked out the GW store, at least the Canadian site. Tyranid boxes look a bit different.
Carnifex, Biovores seem new Not sure about the Trygon. Never noticed the Mawloc and Trygon in the background before so may not be new. While Warriors, and some others look the same, but the borders look different to me. Some ribbon or rectangle on the top left border. Could ths be the new border how 6th edition is going to look? Not idea.
Please correct me if I am wrong. If this is new, what could it mean? Again, sorry if this is in the wrong section.
