...I don't see long-running games and tourneys as a bad thing. Most of the PBEM games I've played in any community (Cat23, ACD, and now DC) have typically been at least 6 months, some lasting well beyond a year. Those are the best kind of games - plenty of time to ponder and really shine to the best of your ability.
Now granted, finding GMs willing to run such games can be difficult, and you almost have to allow for GM and player induced breaks (within reason and specified limits) for no-kidding-real-life-gets-in-the-way-reasons. But if such considerations were allowed (since I have two jobs, and my wife has two plus grad school), then yes, I would be willing to GM such a game, and there's no reason I can think of why two tourneys running concurrently would necessarily be a bad thing.
