So, I went and picked up an LGB6 yesterday!
I managed to get the price down to around 230,000 yen (2300~2400 USD I guess).
Unfortunately, firmware is a wee bit behind here. Still no HDR game mode. Appears to be firmware 4.30.65, though it doesn't arrive until Monday so I cannot be sure. Am I going to suffer using this firmware?
Long shot, but anyone know how long I will have to wait for firmware to catch up? I haven't found any buyers forums for Japanese owners, even 2ch.
I sent an email to LG support Japan in hopes of getting some info.
