The new case standards

[brothernod]

I'm thinking about doing a plexi-case again... it's been about a year and a half since I last forgot the idea, but I just had this great idea for my own unique mod to one...and well I'm curious to try it out and be kewl

but the question is, are there going to be any changes to the standard case specs anytime soon??
I'd like this case to work in 1.5 years when I grab a hammer. Is ATX changing anytime soon?? Anyone know of any fact sheets on ATX specs??

Thanks
