I was hoping Sapience could give a little clarity, or maybe I should say additional info, to the following Q&A from the preview in CSTM:

""Q: Will there be any raid clusters or instances released with the expansion?
A: The old style of raids (raid clusters, instance clusters, etc.) are not being reintroduced in this expansion. Epic Battles will be filling that void at least for this initial release.""

Will any of the existing skirmishes, RAIDS, 6mans, etc. that are ALREADY scaled be further scaled to 95 with Helm's Deep?

If not, will the current Challenge quests continue to be available when the instance is run at level 85? I assume that if they are scaled, the CM quests will only be available at 95, but what about if they are not scaled?
