Following Blizzard's announcement that WCS 2014 will no longer include OGN as a broadcaster (as well as GSL being the exclusive WCS Korea format for 2014), even though OGN still has the right to right both Starcraft I and II tournaments alongside WCS and WCS Global events which offer WCS points, OGN has announced a major shift towards hearthstone. Including key casters switching over including their main SC2 casters Themarine and Gorush, Lee Seung Won has already transitioned to full time Dota 2 casting.
There is also speculation that since OGN has no real plan or incentive to host another OSL, that they wouldn't host another SPL either.
