To be honest I don't really miss anything. The deluxe mainly had the advantage (if you can call it that) of "flair" over the pro. Like an added small heatsink underneath the processor socket, the POST code display on the bottom of the mobo (which I thought was neat), and the USB 3.0 drive bay that you can put at the front of your computer. The Z68 V-PRO comes with a back panel USB 3.0 slot so you still have the extra USB 3.0 connections just at the back. I never used the USB 3 at the front anyways, since I don't have any USB 3 devices. I just use the USB connectors at the front of my case.
That's pretty much it really. I would have gotten the Z68 Deluxe but that one is basically a P67 Deluxe repurposed for Z68 (several reviews have said so), so for example it doesn't even have connectors to take advantage of the IGP which is kind of the main reason for the Z68 in the first place (to merge P67 and H67), even if I don't intend on using IGP much.
In fact when I got the P67 I realized it was mostly just little touches like that, but technically it seems like the Pro is more or less the same, minus the flair. And since I'm getting a refund for my Deluxe (it's pre-B3), I'm actually saving money by going for the V-Pro, which I know will suit my needs having used the Deluxe already.
So yeah I liked the Deluxe, but this is practically identical (you will see), and I don't need the extra flair.
