Im not sure why everyone is so sure that TNA is splitting up their tag teams they have left. Shelley and Sabin will be back, and noone will remember the dissension that was "teased" between them, especially creative. Doesn't anyone find it a bit telling that Sabin hasn't appeared since Shelley's been injured? I think it's very telling, and it shows that TNA's plans for them are to remain a tag team.
Im going to go with the belief that the Moore/Neal dissension is simply a way to turn both heel. We might see Moore riding Neal for a few weeks, but Neal eventually "getting it" and turning with Moore. As for Generation Me, the most I expect is for them to have a match or something, and hug it out afterwards.
So in a nutshell, unless someone knows something I don't, I'm not worried about the tag team division. I think 3D will eventually be back as a tag team, even if it means Devon turning heel alongside Ray. The Guns will be back, and as a team. Whatever dissension there was between Generation Me will likely blow over due to "competitive nature" in wanting to win the X Division Title, rather then a full-blown split. And Moore, I suspect, will truly take Neal under his wing and we'll see another heel tag team in TNA. If Jeff gets straight, we could even see a re-united Hardy Boys challenging Beer Money. I don't know the whole situation, but it could turn ou to be a blessing in disguise for TNA in that the mess at Victory Road may force Jeff out of the main event and have him take a "backseat" into the tag team division, where he had quite a bit of success, if i recall corrrectly. If TNA does one thing better then anyone(except maybe ROH) it's utilize their tag teams. And Im confident they'll get it right here, and maybe be stronger then ever as a result.
