if everything checks out with these what is the turnaround time till we have them in hand?
Turnaround is 3 weeks (1 day to run them) and 2 and a half weeks in the ocean.
Also, what are the final dimension differences for inserts, compared to UGCs? Are they just going to need new wider spines?
Not sure yet,

I'll see if I can get an exact dimension on them and post a size.
Another question for the beta testers. Can a super game boy cart fit?
Are the future snes / n64 cases, also going to be "DS style"?
I have a SNES Game Genie and Super Gameboy, tonight when I get home I'll see if I can find them and post it.
And yes N64 and SNES/PAL/SFC cases will be the exact size and appearance as these. I already for see clients buying cases from my site and be upset receiving a nice case for the NES then a UGC for SNES and N64. LOL ...oie >.<
