Predictions on the Crimsonwood Keep expansion?

I was reading the quest data from Elpam Gorlab and Jack Barricade, and it's definitely possible that inside The Keep are the 4 corrupt Crimsonwood Grandmasters from Versal, as a PQ or multi-boss fight of some sort. It sounds deliciously epic.

I have to agree, I presuming that CK would be similar to the KMS Time Temple where there's a mini town at the start and there's 4 bosses at the end. I'm also guessing that there would be lvl 100+ mobs inside too...
