Well, I don\'t write professionally, but my brother does, and he tends to be in the know about things. I sent him an e-mail with regards to the question. He\'s usually busy though, so who knows when I\'ll get his reply =/ I\'ll post here when I do get it though.
As for my opinion though. I could see this happening. In my opinion, movies are fairly short in comparison with computer games (particularly RPGs) So, more time, and money is used in creating music for the games. I don\'t really know how much money a single game would make compared to a single movie...I guess it depends on how well they do. But...I will say this: Music in video games has come a -long- way since the 80\'s (remember the 8-bit music on the NES, or even the stuff on the C64 or the good ole TRS-80?) Movie/cinematic music has also changed a lot, but ... I can\'t quite put my finger on how it has changed. Something about the feeling, maybe moving more into an ambient feel? Not that it\'s a bad thing. Some movie music is very nice...i\'m quite fond of Danny Elfman\'s stuff ^_^ However other music is just kinda...i dunno...there.
I remember my brother remarking on some of the stuff in CSI (not a movie, but still works for the point) and he commented on how simple the music in it was, and yet the person who created it was probably getting paid a boatload.
Anyhoo, three game music composers i\'m fond of: Motoi Sakuraba (Star Ocean/Xenosaga), Jeremy Soule(Dungeon Siege/Morrowind/Kotor), and Koichi Sugiyama(Dragon Quest 1 thru 8 ). I can\'t remember who did the music for Xenogears, but I think it was also Sakuraba. I\'m particularly fond of Sugiyama\'s music. It just seems so creative in nature...well..to me at least hehe. Soule\'s music is often very ambient in nature, much like some film scores.
Now...whether videogame music will be the future or evolution of movie music or not...well...I can\'t answer that. I don\'t know. But I do feel that in the last 5 or 10 years, game music has certainly approached, and in some cases surpassed the quality of music in movies (well, in my opinion anyways) So...yeah...I think I could see the potential for game music to surpass movie music. Whether it will or not remains to be seen I guess.
Just my 2 cents. And e-mail sent ta my bro heh.
edit: I realize I kinda missed the point here, and got off track. the furture of film scoring itself being in games? yeah...I think so. I mean, I can see it...particularly in role-playing games. I mean...you\'ve got around a 40+hour game to fill with music. That\'s a hella lot more room to play with than in a 2hr movie

And when you figure in time spent with the team, royalties, possibly commercial/advertisement, and doing music for that...yeah...I think it could be quite lucrative. Of course...the hard part is getting IN to that industry. Just my opinion though. I kinda hope to get there myself someday, but right now i\'m still a budding amateur

edit 2:
go to
http://www.ocremix.orggo to their remixing forum, and search. I remember reading a topic similar to this at some point...well...maybe not this, but in dealing with getting into the industry. Also, a lot of the remixers there write music professionally. One of em works for Midway Games. Think it\'s The Wingless who works for them. Not sure. Worth a look at any rate ^^
