Not much is known about Bioware MMO but I am sure it is for PC because MMOs are in most cases PC-platform specific and go onto consoles secondly. Seriously, MMOs are a big part of what is making PC gaming not go extinct. World of Warcraft is the prime driver of all PC gaming. All the money made from subscriptions really does make a difference in the investor front. However, PC gaming will never die unless PCs themselves die, which is not likely going to ever happen. If you observe the state of PC gaming in early 1990s compared to nowadays, PC gaming is bigger than ever, there are 10 times more games coming out each year. Everybody uses computers for internet access and downloading music & movies, et cetera. I doubt PC gaming will ever die off in our lifetimes. Actually I think things will only get better for us going forward, especially in the MMO space, due to the improvement of technology and software coding innovations. Of course I am biased since I dont like consoles at all, I do all my gaming on PC. Despite some of my bouts of doubt and frustration, the MMO space is the most promising aspect of PC gaming. Why? because they are the games most funded with the biggest teams and highest levels of technological innovation. Investors are looking at MMO space. I am currently watching about 11 new startup MMO companies that are each funded in the 10s of millions of dollars. Every major MMORPG release brings more and more new players into the space. World of Warcraft alone is responsible for at least 5-8 millions of new MMO gamers coming into the space that werent there before it. Warhammer Online will attract Warhammer fans in general who never wanted to touch MMOs before its release. Same thing with Age of Conan fans attracting the remaining fans of Conan fiction. Bioware MMO is supposedly so huge that its developers expect at least 1 million subscriptions upon immediate release, even though we dont know what their project even is yet. That means its a huge thing like maybe Star Wars KOTOR Online or maybe Forgotten Realms. So whatever Bioware is coming out with, its gonna be huge, and you can bet its gonna be on the PC.
That said, single-player will never go away, it will have up and downs like it always has, but the current fad really is online gaming. As broadband becomes more accessible to more people, online gaming is just going to get bigger and bigger. It has already overtaken movie sales in the United States. Approximately 1 billion dollars was made in MMO space in 2007. Estimations state that the MMO space will become 1.5 billion dollars come 2011.
