Ah ha! There is the problem. I have xposed framework installed, that is why it kept reverting to Dalvik. Not giving up xposed so I guess I don't get ART until it's supported by xposed.Decided to put some extra notes here for those that only read the last page.Also put this in the OP.
Just a reminder regarding the newer recoveries, CWM 6.0.4.5 and TWRP 2.6.3.0, they are in flashable zip form on succulent's blogsite linked above. You should be reading his blog info anyway, so just scroll untill you see the links for those recoveries. If you run into a problem flashing the zip, one of the simplest ways to get the job done is with Flashify. Just unzip the recovery zip to get the image file. Put the image file on your device and flash it with Flashify right from within you current OS, ie; CM10.2 etc.
Regarding ART runtime: Since it's still "experimental", YMMV with the results you get. Also, Google may decide ART isn't feasible and dump it going forward.
A couple of things to note, not all gapps packages are ART compatible, the gapps I linked from 1209 do work, I'm not sure about the ones linked on succulent's blogsite from 1208. I believe the PA zero day gapps are also ART compatible.
With ART runtime, it is generally better to initiate it on a fresh rom install and before you install all of your user apps. Btw, it's normal for it to take a long time to initialize on the first reboot. I found that it generally takes a while to "settle in" and should become more fluid/speedier overtime.
Always be sure to have a nandroid backup so you can easily go back to dalvik if ART isn't your thing.
One last thing about ART, Xposed Framework does not yet support it. It will appear to work but it does not. Matter of fact, with Xposed installed on your device, it will revert ART runtime back to Dalvik. Since I love using Xposed, this has kept me from using ART except to test it.
