It's not clear who to thank, Sony, Activision, or Harmonix, but a great thing has happened. Hidden in the patch that fixes compatibility in the downloadable PAX pack for Rock Band is a great feature that has been missing from the PS3 since launch: your Guitar Hero controllers will now work with Rock Band on the PS3.

The 360 controllers, pictured above, have played nice since launch. Gamers will be happy to have their PS3 version finally catch up. This confirmation comes from Matt, an OT reader, who sent me the following note.

Well, last night, they put out an update for Rock Band, I guess, and it fixed the songs. But even better, my GH3 guitar now works! I'm pretty stoked.. just finished playing through a song with my housemate on two guitars for the first time ever on my PS3.

Sony has claimed that it was working on a fix to all the conflicting plastic instruments, and it's awesome to see something finally come of it. This was a rumored feature of this latest patch for a while now, so we're happy to hear the games are now compatible. Now let's focus on making sure the ION drums work perfectly with World Tour.
