In a word: No.
Although I still believe Redguard has a good chance of being our next major Skyrim DLC (it may even come out this summer), the video currently making the rounds online is using a screenshot that is, in all likelyhood, a fake.
So the story is: a user just happened to catch the Steam page at just the right time when they had accidently posted placeholder for Skyrim's next DLC.
Well, as much as I'd like to say 'I told you so' again about some of my speculation, this is not the proof we are looking for. Sure, the price being 'wrong' is due to the shot being from overseas, therefore it's not actually wrong, but that's about the only thing they got right here.
First of all, where is Dragonborn DLC in this screenshot? And, if it was a new item, there would be '11' items on the list, not 10 as there are currently for Skyrim's Steam page. Debunked by Yong and some of his fans pointing out that the Australian version of the Steam page only has nine items and begins with Dragonborn. Though no answer was offered on the other issues:
Second, Bethesda really used a shot of a character (in a modded version of the armor it appears!) that you can easily pull up in a google search as their art? Really?
Third, this is not really something that would happen this far out. Bethesda couldn't even give us an extact date on Dragonborn until they were 100% sure it was ready, and that applied to vendors as well, even they didn't know before we did. Not to mention, there is just no need for them to send steam a mock-up or placeholder for it months in advance. Also, there is a good chance we'd see a trailer up before something like this.
It would be awesome to get confirmation on the Redguard DLC, but I think we will see something for Dishonored come out next from Bethesda in the way of DLC, and while we wait, maybe, just maybe something will come out in a patch that leaks some data. Patch 1.9 is out now and I have yet to see anything come of it's code, so we are probably still months away from getting a better idea of the next Skyrim DLC.
I have no problem speculating about something, or even reporting leaks and rumors you aren't one hundred percent sure of, but tell your readers (or listeners) that. Don't state that it's a sure thing when it's not. If you want to check out the best speculation on the next DLC and all the info that actually applies, check out my previous article here.
The Youtuber has made a new video and has removed the older version. He has apologized for stating it as 'confirmation' and the new video addresses this as a probably fake screenshot.
I'm assuming that my top rated comment on his youtube page sitting right at the top might have made him reconsider the approach of the video, though many were echoing some of the same ideas as me in comments. As to the hundred responses I got on youtube that I cannot answer now becaus the vid is deleted yelling at me about the fact that the Dragonborn DLC shows at the top of the list on the Australian search: I'll offer an apology as well for only three of my four reasons this was a hoax being correct. I'm lost over such a tragic mistake.
