They say it's much more bigger and complex than Sekiro but you can't deny the pattern here. They could give us something at this point.
The delay of information is making me a little more excited tbh. I love how they are aiming this to be their most ambitious title ever.
Personally I'd rather them show the game when it's almost finished and end up releasing a few months later than show us some footage now and having us wait another 2 years + potential delays. The one thing I have to give FS major props on is that they have not disappointed in the last 6 titles they've released in the past 10+ years. All have been great games IMHO.
I also love how Elden Ring won the vote yesterday for most anticipated game among giants like Zelda, Halo, and God of War... that's really amazing.
