URGENT: GSL Finals - When are they?

Hey guys and gals,

I booked my flight to Seoul not too long ago, but I fear I may have got the wrong day.

When exactly are the GSL Season 2 finals?

Liquidpedia says season 2 "ends" on the 28th. While the WCS page says its June the 2nd. Which it definitely is not.
So when is it, and what time? Please help!
