Nevermind, see below 
, sorry for the false alarm!
While on hold with Airtran, one of the advertisement/messages had revised one-way flights required to earn Airtran Elite status... possibly putting it closer/in-line with A-List Preferred (A+) on SW. The revisions are not updated on the website from what I can see. Luckily (cough), I've already listened to the message three times while on hold to verify what I heard
.
New requirements (possibly old, un-updated requirements):
20 one way flights in 3 months
50 one way flights in 1 year
Old requirements (possibly just the current, updated requirements):
10 one way flights in 90 day period
25 one way flights in 1 year
Unknown requirements for renewal of elite status -- mine still states 12 one way flights needed (10 remaining in my case).
