Erm, where did u dig up that piece of usefull information..lol...Please refrain from making comments about things that u have no idea about.
As far as I know Activision is in charge of marketing any game they publish so why would that be any different for Doom 3?
I can guarantee I have alot more know-how than you do about how software companies function internally. I've worked for Electronic Arts in the past, and currently work for a web development company.
I fail to see what your arguement here is now other than to be a troll. Its obvious you are just trying to be an antagonist, so I'll bite.
Activision indeed pays their bills (but Im sure id has their own money invested too), and I dont think you have a single clue as to how expensive it would be for both companies to "jump ship". Doesnt matter if there are 100 publishers lined up outside, after 4 years of development, and millions of dollars invested Activision cannot just be fired.
If you really think Activision is going to hang a sign that says Doom 3 2003 without calling up John Carmack and saying "hey, is Doom 3 going to be done in 2003? We plan to hang a sign at E3" You are sadly mistaken. Again I don't think you have a freaking clue as to how anything works in the corporate world.
