These are no "wrasslin'" rags.
Yeah, not knowing her, specifically, I think this is probably what's most likely.
I actually think the CM Punk route is what's most likely for her.
Now, I don't think she'll be doing MMA, but she'll probably do some passion project (indie movie, indie album, maybe wrassle in a few indies or Japan) and mostly stay low-key for some years.
I haven't heard her say she wants to take over Hollywood or music, or whatever.
I could just imagine a world in which she just goes home for a while and emerges when she needs some money or after Vince is long gone from WWE.
