There's definitely something to be said for letting players dissect and figure out the game before it gets patched. Something a lot of e-sports could do with a little more of.
As for Ken, he just recently returned to the scene.
He went inactive for about 5 years, but came back in 2012. Hasn't been doing nearly as well as he used to though. After 5 years the metagame kind of left him behind. He made it onto the 2013 power rankings, though only barely at spot 100. Recently he was given a sponsorship by Team Liquid so he's been getting a lot more high-level practice, and he even finished 21st at MLG this year, outstripping a lot of people who outranked him on the 2013 list. It'll be interesting to see how far he goes. Everybody loves a good comeback story.
