In a 10-Q file recently submitted by WWE, they included a "Booking Agreement" with Stephanie McMahon, reports PWInsider. The agreement is valid for three years, effective from October 7th, 2013, and is made out like a wrestling contract. She's even referred to as 'Wrestler' in the document.
This doesn't necessarily mean Stephanie will wrestle at some point during this time period, but it's interesting to note WWE filed it, allowing her to work a match if they so choose.
If memory serves me correctly, I believe Stephanie's last match with WWE was at No Mercy in 2003, when Vince beat her in an "I Quit" match.
Davey Richards/Eddie Edwards Update
Ring of Honor stars, Davey Richards and Eddie Edwards, since working a recent WWE tryout camp, have reportedly been on WWE's radar. Richards gave more reason to speculate when he teased going to WWE in a post-match promo yesterday at a Preston City Wrestling show, according to F4WOnline. Although Richards never mentioned WWE by name, those in attendance claim he definitely implied it.
