I received this information few days ago:
“Olympus Australia are going to start giving away a FL-36R or Vertical grip with E-30 kits from the first of June. Because they feel E-620 has been taking sales, and the E-30 has not been as popular in Australia as it has in the rest of the world.
Panasonic Australia are expecting a delivery of G1H around the 10th of June, they should be in the stores a few days after this.”
Many thanks to the one who gave us the info!
