I'm not sure how it's an S3 killer, as the article says:
Pantech, being mostly Korean smartphone maker with very limited distribution abroad, chose to do its new flagship as an exclusive project with SK Telecom. Vega S5 comes with its own, carrier customized Android skin/apps
, and chances of you getting it outside of Korea are close to nil.
So, they're not exporting it, and aren't likely to do so. Then the speculation:
Still, if Pantech can do it in Korea, maybe they’ll decide to expand with the new Galaxy S3 killer abroad too. Or someone else, like HTC or Motorola, will take a hint and release something like it this fall.
In other words, maybe someone else will release a phone with higher specs than the S3 in the future. Really? Who would expect that?
Silly article, silly commentary, non-story outside Korea for the time being.
