> korean cybersport is finally transitioning to SC2
Yes and no. Proleague finally switched from Brood War and KeSPA players are doing excellent in the WCS leagues, esports in Korea are way down from where they've been, with MBCGame dead. Even then, almost everyone is playing LoL.
In fact, in PC Bangs, Starcraft 1 is STILL more popular than Starcraft 2.
> diablo is fine
Again, yes and no. It sold well, and the initial sale of a Blizzard title is where almost all its revenue comes from. But many, many of the most hardcore fans were disappointed, and most won't buy the next Diablo property 'sight-unseen' like the last one.
> wow is probably holding record for the most living / profitable mmo
True, WoW has been the most profitable MMO ever. But their numbers have declined over the last few years, and every attempt they've had to "give it the paddles" and reignite growth hasn't been too successful.
Almost all my friends who played WoW call it a shadow of the game that it was, citing the HUGE differences in skillsets and builds, how easy it is to get rewards, etc.

All that said, SC2 was a HUGE part of eSports rising worldwide, and still sports a pretty healthy audience. And one has to expect their next MMO will be spectacular, if they can ever abandon WoW.
Speaking here as someone who has played WoW since vanilla, that's sort of a self-selecting sample. Your friends who used to play WoW are people who selected into enjoying it when it was a (by modern standards) relatively hardcore game. It makes sense that they might be turned off by its new "everyone can see all the content!" approach.
It wouldn't surprise me if their current subscription "woes" (quotation marks because they're still the biggest MMO around) stem from the more-casual userbase running through, seeing everything, and not having any really reason to stick around, instead canceling their subscription until the next big content drop.
Am curious why you put that qualifier in. Is it just that you think people have to play MMOs to become bored of them?
Another few years of that and they'll merely be ... well, still the largest subscription MMO ever...
However, WoW simply is more playable than its competitors. I played a few of them, and WoW was still better. The next MMO to carefully build itself to be super playable will be quite a hit, I think. Note - when WoW was released, mobile wasn't here. If most casual gamers have moved to Facebook/mobile instead and won't get a desktop to play their MMO, the market will have shifted such that there won't be another WoW.
