Alrighty. I’m writing this based on what I’ve seen and read from many sources.
And I’m not saying at all that this is certain. So just take it as you will.
From what I gather, it started with someone named Des Desworth (which is an awesome name if it’s real), and a group called Piece Out, that apparently lives on Facebook and Youtube and stuff. Apparently this fellow (who, I think, works for LEGO) has leaked stuff before, and had it turn out quite correct.
Sometime on July 1st or 2nd, there were two photos leaked. This, from what I’ve heard, was released first. “Eh” is pretty much my feeling on this one. It might be legit, it might not. It’s rather hard to tell. A few of the images look like previously-released Bionicle sets. I’m not sure on it.
This is the second one, and it holds a lot more potential, in my opinion. A lot of people have said that the sets look like ones already released. The only one that I see that possibly looks like it could would be the one on the top shelf, right side, which, as I write this, I realize looks almost identical to the middle-right set on the first photo. (Adds a bit more plausibility to both, I think.) Anyway, this somewhat looks like Hordika Matau in this poster from 2005. Doesn’t look enough like it to convince me, though. Also, there is a SIX legged spider thing which people have argued could be a Visorak prototype. Visorak have four legs. Not six. Plus, the body shape is very different, so I doubt it.
Based on these two, people have said it might be a prototype display case from 2005. But just look at the banner thing above it. Toa-design is completely different, there wasn’t really (well, there was a supposed plot idea with the Mask of Light, but that didn’t happen) any mask-related stuff in the Hordika line, and… Just… It doesn’t really fit with it. The font on the side, that says “BIONICLE” is one that I don’t think we’ve seen before, as well.
Also. You can see a thumb, at the bottom, holding the paper or whatever it’s on. Next to it, you see “Wobbler (2 in a set). Order seperately [sic, should be separately].) A wobbler is one of those floppily-attached tag things that you see in stores. Interesting.
Some people say they think they see Hero Factory-era pieces in some sets. I don’t see any (mostly because the image quality is poor, but also that I wouldn’t really know what Hero Factory pieces look like).
But there’s another thing. As soon as this stuff came up on BZP, Black Six got really up-tight about stuff, then, a bit later, so did Makaru. Now, it is well known that BZP has ties with LEGO. (Not saying this is bad, but it can cause some liability things.) It could be that Black Six got news to close stuff up about it, so he did. I don’t blame him. But this adds another layer of possible intrigue with it all.
