The wavy letters in the title also feel like the glinting reflections of light on the surface of moving water, like the images shown on the logo trailer. It's also interesting that the "blood" is in quotations in the trailer. Will blood be just a symbol of something else, less direct for this era? After that sentence a sunset sea is shown with the way the lighting it kind of looks like blood to me.
The orange from the logo is very matching to the orange we had for manifesto but I think it's a tiny bit more on the sunset side. The color and the trailer feels like a theme of reawakening or bittersweetness.
Apart from the "manifesto orange" the imagery from the trailer makes me think mostly of bd:o and d:d (but no specific connections just feels) I'm really unsure what to expect but it makes it exciting.
I also had a theory from the closing of the concept trailer that this era will be connected to the sun. They had 3 words highlighted: Darkness > Dark Blood Sun > Orange Blood? (My guess was bright blood lol) Eternity > my guess was eternal blood but if we are going with colors not sure. Emerald Blood is still on my list somewhere.
