My Predictions for Gridrion and Glory :
Gridiron - Definite Bloodbowl, in-depth look at the new Season 2 Box, 4th Team Announced (If we include the Undead from the other month)
Glory - Probably going to be Direchasm. Full look at Lumineth and Slaanesh teams.
Would also vouch for it being a look at Warcry Season 2 - Possibly showing as to where the additional warband boxes are going to go and I'd certainly guess it'll to be focused with non-Chaos forces in mind. I can't see GW making 8 Chaos Factions and only having 1 other non-Chaos faction represented with custom faction elements.
I'd guess with the theme of "Catacombs", they might have a look at the ugh "Darker" factions (hence the Shadowstalkers, bc whats spooky scary than spooky scary assassin elves with spooky shadow cloaks?).
Could be where the Vampire/Soulblight rumour engines are heading towards, with new sculpts for Warcry maybe?
More likely they'll end up with the Direchasm though.
Wouldn't surprise me at all if at least one of those pays off this Saturday, but if it doesn't... I'd call Soulblight for Christmas.
I don't really expect anything for 40k or AOS though, there seems to be a massive backlog in the other games and I'm guessing they'll be the push towards Christmas, minus the Broken Realms AOS Book and the remaining supplements/models for 40k.
