I've heard that too (I think it was a rumour I heard though, not a video), I've also heard there will be no such thing as "combat levels" outside of combat-zones (meaning they won't appear, it'll just be the persons username). I have no idea. Personally, I'd like them to completely revamp it, I mean, it's totally unfair really the way you can "over power" at certain combat levels. Maybe they'll do-away with attack/defence/strength levels (they only work when not wearing weapons/armours) and your overall level will be determined in what weapon/armour you have, which means you technically could be level 3 (1 att, def, str) but have the best gear, giving you a "visible" higher combat level, I think that'd be quite interesting. Or, armour reflects your defence level, the higher it is, the better the armour becomes, same with attack, hopefully this would stop people having low-defence and low-attack.
