Hey guys!
Have just picked up the latest copy of the UK edition of White Dwarf, and there is a good suggestion that FFG might actually be there.
On the Games day map there is a long dection called 'Licensed partners', and within the text contained on the same page there is a passage which mentions many of their licensed partners will be there to display their boardgames (and pc games) based on the Warhammer and 40K universes.
Ok so its not conrete evidence, but certainly a hint potentially.
Either way, I'm packing enough money for 3 bases sets just in case
