the type is from Gen 6 which people took to reference Aegislash. (EDIT: ninja'd)
Speaking of which, recently he's
addressed the website with a reminder of the coin post, said
Hoopa has a chance to make it in, made a
poll about paradox Virizion's kept type, a poll about the
sushi relationship, a
vague riddle about which generational gimmick is different, images of
Cobalion's chest/Terrakion's legs/Virizion's head which may also be about paradox Virizion with the hint mentioning imagination, a
relationship between the hammer and a Gen 8 mon that may relate to a tweet where he said it
hits birds and which some people think it means a smack down effect, some possible
body shapes for paradox Suicune, a
knot that apparently represents a new mon, and a
color hint ("red & green, 2Hs") that may be about the pepper. It hasn't really revealed much but that's what he's been posting that hasn't been posted among some other stuff for reference.
For the chest website, apparently there will be an update after 1/5/9/13/17/21/24/25 hours from start.
Here's a snippet from the javascript used for reference with time being in seconds.
The images from
box02_01.png to
box02_05.png shows the chest filling up with coins in the 2nd angle.

I got this image from
this site but I don't know if they took it from someone else.
