Just spoke to one of the sales guy. Quite amusing. Below are his points
1. They are not changing the sensor for X10, only changing the firmware to latest. There is no word from their jap office on the sensor change as well (This is quite a shocker as some of the other users here have their sensor changed already!)
2. He spoke to many professionals and they say it is a very rare occurence and it happens to other makes as well (I sort of agree that it happen for other makes but the orb is more unique for X10 as they are using EXR technology)
As usual, he gave me the sales talk and how he has confidence in this product. I don't fault him for this as it is his job.
All in all, I will still take the leap to purchase X10 as it is still an awesome camera :bsmilie:
