It's not a big enough market people wanting to use KB/M, sure for this post people are going to reply "well I do!" for the next 30 posts not realizing they are the fast minority. Even on UT3 that has KB/M support on PS3 I think they said somewhere like 0.3% of users use it. Developers don't even have to implement it, just enable it to. KB/M on PS3 is standard with any generic usb KB/M, the software to handle it is already encoded. You can use a KB/M outside of games. Besides, you can buy adapters so you can use KB/M on PS3 games, vast minority who actually want it will do that.
