its impossible.
do you realize how long it takes to reach WXGA from VGA in the mainstream market?
the current Retina display market is still niche, and you're expecting a 4k in laptop?
keep filling the pipe with those dreams.
I didn't say i expect it. I said its a possibility but just as last time you don't understand.
Many brands are working on 4k laptops for release during the second half of 2013.
So for Apple to release one in October is not such a impossibility at all.
