I used to be into the Old World lore many years ago. My friend's brother played WHFB and sweet Skaven and Vampire Count armies. The game looked great, but the lore was what grabbed me.
Then GW nuked it for AoS. I've tried getting into AoS, but it's not doing it for me. It doesn't have the same Old World vibes and the game doesn't look the same. However, I'll certainly be looking into they're release of The Old World game. AoS, lore and gameplay wise, just isn't for me.
I guess a lot of people felt the same, which is why they're bringing back the old world to tabletop. I have a feeling it'll be a massive hit for GW.
Probably the best bet is the Warhammer community site. It has the news on the latest releases of everything GW related.
