Holy Lord.
The theories and posts on reH in the Resident Evil 4 topic have been blasting away like there's no tomorrow. Something like 16 pages have been posted within a day.

In the TGS trailer that was already provided, the comments at the end of part eight have been translated:
"The Bell!"
"It's time to pray."
"We have to go."

Hundreds of theories include that this, "Lord Zatler" is in fact Lord Spencer and that this village may be where the Progenitor Virus was first created. Regardless, this is getting really interesting.
Also on the trailer, we see a quick glimpse of a woman in a red dress shoot at the villager chief who knocks the Hell out of Leon. By pausing the video RIGHT at that moment, there is a major resemblence to someone like Claire Redfield or Ada Wong. This might continue on with the rumour of 4 character from previous RE titles being in RE4.
Once again in the new trailer, we see that in the last few seconds there is a monsterous claw in a fire. Could this be another Tyrant or some sort of new monster?

The dialogue of the characters have also improved and when Leon informs Luis of the Raccoon City incident, I almost had an.... ... ....Ok, let's just say it was interesting.
