Here is another long awaited update (mostly because I got an email 5 hours ago from zF)
Good news and neutral news.
Good news first, sets are being sorted and prepped for international shipment.
Neutral news, JTK made some layout changes without notifying anyone. I will say, these are all changes that don't negatively affect anyone unless you really liked the ⌫ backspace.
Here is the list of changes:
Added:R1:1u JTK logo, ←
R4:1u Pgup, 1u Shift, 1u Ctrl (extra), 1u AIt (extra)
Changed:R2 1.5u ⌫ to Backspace
R3 1u 5 homing bar to nipple
R4 1u 0 doubleshot to 0 with Ins tripleshot
Removed:R3 1u scooped 5
Here is a side by side comparison
JTK Griseann
JTK Royal Alpha
Also to answer the question of if they ship in JTK trays, I know that the base kits will ship in trays. I am unsure about any of the add on kits (accents + spacebars)
