Here are some updates from retailers on possible Wii accessories:

  • Silver Wiimote
  • Blue Wiimote
  • Pearl Pink Wiimote
  • Silver Nunchuck
  • Blue Nunchuck
  • Pearl Pink Nunchuck

These are said to release June 29 in Europe.  I would label this as a rumor for now, but the retailer lists are usually pretty reliable.
