Does anyone else have experience with summer super savers?

I'm planning on going to CEB for summer vacation. It's also the peak vacation week for Koreans (July 27-August 4).

Last year, when I went to Vietnam, they had a Super Saver in late May...for the same July travel dates.

What's the probability that they will do it again this year? I'd guess pretty likely, right?

Super Saver fares are K class, right? As of today, ICN-CEB is only showing M and higher (922,000 KRW). E is sold out. ICN-MNL, however, has E class at 722,000 KRW all-in (the CEB E class that was up a few days ago was this price, too)

.....and we could catch a cheap Filipino airline for like 30 USD RT all in MNL-CEB.

Thoughts? Buy MNL or cross my fingers and wait for a CEB saver? At best, I imagine I could get Cebu for 650,000-700,000 KRW all in...but I hate waiting for summer sales.
