Cry as much as you want, but the PS3 version is here to stay, and PC gamers that actually know how this works have nothing to worry about it.
You're right, it is here to stay. I'm not crying- I'm simply posing a logical argument about what would be better for the game- regardless of whether or not it will actually happen.

Nope. The problem does not exist, as assets can be downgraded with a single click activating a batch operation.
The problem does exist. batch-downgrading assets doesn't solve the issue at hand.

There's no reason to believe that support will be dropped any time soon.
Who said anything about soon? It took 10 years of FFXI before PS2 support began the process of being dropped in FFXI. It *will* happen, eventually. Then you'll have a million threads bitching about the support drop and how "we're still customers too" and "we shouldn't have to buy a new console to play the game" - and on that last part, I agree- if only they bought a PC, it would have lasted longer before even needing upgrades, and you could perform those upgrades for less than buying a new console.

And? It doesn't matter of the PS3 version is held back. That's the problem of PS3 players.
A problem that is better solved by not having the PS3 version at all- The extra customers aren't worth it when they become disgruntled squeaky wheels years down the road.
