I just saw a poster at GameStop today advertising that you get an extra 50% TIV when you trade PS3, 360 or Wii controller towards a PlayStation Move. I didn't really get a good look at it since it was high up, but it looks like there is also some other deal with the PS Move bundle. I asked about the TIV for a Sixaxis and it came to $11. I'm probably going to trade in my Sixaxis that came with my PS3 since it disconnects from time to time.
