Sounds to me like someone is trying to do damage control to make EXCUSES for why this game is probably going to be BROKEN when it's released..
I mean the game is about to come out.. honestly why is this news coming out mere weeks before release? It sounds to me like they KNOW the game is going to be a disaster with broken gameplay, but instead of concentrating on making it a quality title, they are laying the tracks for the blame train to run on the direct line to Rockstar NY.
I was extremely excited about this game.. i've been waiting for a GTA style game set in the west ever since Gun which I thought was phenomenal even if it didnt sell well and for the first time out doing a style of game like that. I'm a big fan of westerns, I watch them religiously, and I still watch and tivo Gunsmoke and Bonanza.
Now though i think I'll wait good and long before buying this for fear it might be a pile of crap, which is NOT the sort of opinion they want to cultivate before launching a game... otherwise the game's failure will be a self-fulfilling prophecy.
