Believe me, I have always doubted thedroidguy. Don't think there hasn't been anything credible to come from that site that hasn't already been known. Kellex on the other hand is someone I trust. His reviews are top notch and his information has been quite good in the past few months.If you read through the comments in the Droid-life article it is obvious that Kellex knows a bit more about this device then he is letting on. He seems to be posting the information from droidguys site because some of it is indeed credible. Kellex posted this information instead of his own to protecting his sources (seems to be self imposed NDA).
What I think is confusing everyone today is the slide out keyboard debate. Kellex seems to be adamantly against it being VZW Nexus device. And in his defense, there has been zero mention of the Nexus Prime having a slider in any "leak". Hoax leak or not, it wasn't until Panda that we started hearing about one and its pretty late in the game for a phone that will be shipping in November.
There seems to be three phones being talked about here. The Galaxy Nexus (sounds like there could be Droid branding) appears to be the VZW phone and I will put money on it not being a slider. With the Stratosphere coming out in the next month and the Droid 3 still being quite relevant I doubt that another slider is on its way. The market for them is not nearly as large. It also sounds like this is not a true Nexus device. Although at this point I think it is too early to tell. The Nexus device that everyone on here wants sounds like it will come out shortly after the Galaxy Nexus, probably closer to the Holidays.
As for what will be on these phones. Who knows. There is a description of the Galaxy Nexus in the droid-life comments which Kellex agrees with. They seem reasonable but still very much speculation. My guess is something more solid will be coming in the next two/three weeks, especially if the Vigor is indeed coming out in mid October. I'd expect a good amount of "leaks" of the Nexus prior to Vigor's release.
