They're actually referring to a bit of dialogue that was leaked out from the script, a few words of which may have been part of the trailer. This is apparently from when Evey first meets V in the alley:
V: This visage, no mere veneer of vanity, is it vestige of the vox populi, now vacant, vanished, as the once vital voice of the verisimilitude now venerates what they once vilified. However, this valorous visitation of a by-gone vexation, stands vivified, and has vowed to vangquish these venal and virulent vermin vanguarding vice and vouchsafing the violently vicious and voracious violation of volition.
The only verdict is vengeance; a vendetta, held as a votive, not in vain, for the value and veracity of such shall one day vindicate the vigilant and the virtuous. Verily, this vichyssoise of verbiage veers most verbose vis-à-vis an introduction, and so it is my very good honor to meet you and you may call me V.
Evey: Are you, like, a crazy person?

Yeah, I read that on AICN a while ago but didn't notice any of it in the trailer. It's probably still there, but I'm just confused as to how someone could come to the conclusion that it's still in there just by the dialogue in the trailer. I already read all the complaints about it earlier, but when that trailer came out, people started posting with "well it seems it's made it into the trailer."
