That canister looks a bit different than the previous one. Also weird that the thing is stuck up in the ice like that; very different than the traditional imagery of them washing up on beaches.
Now, this is completely me coming up with things, but what if this takes a sort of Legend of Zelda angle, with the Toa reincarnating and reappearing generation after generation? The difference between the two canisters is what made me think of it, with the previous two being so smooth, like the ones in G1, while the new one looks far more futuristic and technological. There's also Faber's comments; I remember from his initial post he was talking about "a way back", or something along those lines, and more recently you have his comments about the flow of time through generations, which is shown in the first post. Again, just me connecting a bunch of stuff that probably has no connection, but I thought the idea was cool.
