Just as an FYI guys, the case size has NOT changed at all. The sleeves are being affixed further from the edge, which leaves a little less room for printed inserts. Just print at 97-98% and you'll be fine 
I ordered a used lot of Universal Game Cases from eBay and it turned out to be a Frankenstein lot. Their were 3 different sizes. On some, the spine was wider & others seem to be a larger case in general. Seems that the actual design changed a few times.
I guess I should have clarified that, if you buy them from media shelving, they are all the same (in terms of dimensions) and have been since I've been using them.
However, other companies have produced UGCs. I had some that were about 1/4" thicker than the media shelving cases that I used for packaging modded GBAs really early on.
