Hmm, interesting. I didn't see those the first time but I just skimmed really.
Possible Spoiler Warning:
My thoughts are contained below as to what these images could symbolize. If you would like to keep your thoughts your own without influence from other's thoughts then don't read below.
The Building Picture:
Since MalibuARMY posted that picture of the Jerry's Nugget Casino it is pretty obvious it is that exact picture. They are the exact same size and everything, just the one they put in the email is desaturated and has some type of blur applied (looks like a gaussian blur to me). I can see this being a couple things, but I'm not entirely sure. My first guess would be probably a limited run of Jerry Nugget's cards, though that's usually Lee Asher's thing to do, or something like that (maybe like a new type of card from the casino that is really good too or something). I can also see this being more releases by Jason England, whether another Foundations DVD (like MaxWhattup said) or just another downloadable video. Past those two things I can't really think of much else unless it's like a trick image where they are going to be restocking some Wynn cards instead or something.
"Superman" Picture:
This is an interesting one. The "motion" blur on this one makes it tricky to really decide what it could be. It does look something sort of like some of Homer Liwag's things though, to me anyways. So my guess for that would be it's D1IE that is coming out or something. But I'm not entirely sure if that's it since Theory11 tweeted that the beginning of the shoot was beginning on the 21st, though that tweet could also be a delayed image posted or something (the tweet I'm talking about is
this one). Five days just doesn't really seem like enough time to do an entire production of one of Homer's products. But again, I could be wrong. The other idea that I thought was good, though I hadn't seen it or heard of it until I read it here, was saborfang17's suggestion that it could be Calen Morelli's shirt change effect (can be viewed
here as a revelation). I think this because if you look at the left hand (right side of image) it looks like it is gripping the shirt between the index and middle finger, so kinda like a hint that it deals with the shirt some how.
Deck Picture:
This is another tough one, but more because of how desaturated it is rather than the blur. It does look silver-ish so ya it could be a card clip but I'm not to convinced of that. It just doesn't look like one really, looks to thick and like a full deck of cards. I also compared it to a card clip I have and I think you'd be able to see the hollowness of it from that angel (it also has a line across the top like where light would be reflecting on the box crease for the flap and I don't think that'd be on a card clip). Also, as it does look like the Split Spade logo of David Blaine's I think it is actually a modified DD logo from Dan and Dave Buck. The Split Spade logo is tight together while that looks more separated in the picture. So I believe that is about the release of the new Smoke and Mirrors v.5, especially since I believe JB already has some since he sent some pictures to Dan Buck (look
here for that tweet).
