If you recently downloaded and flashed that MC2, then you do have the official OTA. However, prior to like early June, the MC2 everyone was using was a leaked version that had some MA7 bits in it.
I know that most of the active ROMs that have updated to the MC2 OTA have the usual mods working, but I don't think the individual flashable mods work on the official MC2 OTA -- at least they didn't for me. They worked with the MC2 leak tho.
I'm going to have to check out Xposed. I've been seeing references to that on the forums and I'm thinking it will likely come in handy like when the 2.3 update is released (and likely houses all the mods all over again).
