Interesting spot pattern.... and better than a lot of the other ~newer~ patterns introduced by GPI, imo. Chip color choices are okay. Not a fan of brown chips in general, but this one isn't bad, just not a good choice for a T100.
What is really strange is the inlays -- it appears that they are using the same inlays as before, which were basically color-matched to the base clay colors. Note the gray inlay on the brown T100, arc yellow inlay on the yellow T1000, the blurple inlay on the T500, and the lime green inlay on the T25 chip. Very weird. I think they'd be much better looking if the inlays were color-matched, or all uniform. Adding a fourth major color can cause issues.
Everybody knew that new wsop chips were being made (recent NGC report). What has yet to be confirmed is whether the old 818-spotted set will be used this year or not.
