News sites have been reporting a January release date since December, and the blogger/forum community has been giving the date of the 20th for the 2X in black, and a February release date for the white version.
There's plenty of sources regarding a January release, but nothing concrete on the 20th yet. Either way, the whole country seems to believe we're getting it this month.
Also it seems the Optimus Black will see a very-soon release:
LG???? ??Ƽ?ӽ? '2X????????????' SKT ?? ???3?? ???? ???? ::?????丶??::
Article is in Korea, but mentions how each of the three major carriers in Korea will get an Optimus. LGT: Mach, SKT: 2X, KT: Black.
Will post more as I get any more concrete info.
EDIT: Not sure if you also wanted any information regarding the pricing I mentioned...
Phone is currently believed to be at roughly 1000$ (Something like 1,139,999KRW). I find that to be on the pricey side, so I'm hoping it's just a false rumor. Either way, Korea offers financing on its phones over the period of your contract. You receive a significant discount on the phone price for the two year contract, and also a monthly discount based on the plan level.
For instance, the Galaxy Tab with a monthly 55,000KRW plan reduces the cost of the device to 220,000KRW. You'd just pay a 9166KRW (220,000 / 24 months) on top of your monthly 55,000 (so like a grand total of 65,000~KRW, depending on taxes).
If you were to select the 95,000KRW monthly plan, the tablet is free, and you'd actually get an additional $2 discount on your actual plan.
Note: The "unlimited data" starts with the 55,000KRW monthly plan. It's the most commonly compared/purchased/etc.
