what is the release date for confluence 6.0 for cloud

[Nic Brough [Adaptavist]]

"When it's ready".  Atlassian don't give fixed dates, they release when they're happy with the product.

(Ok, ok, the recent Sourcetree release was definitely not ready, but other than that)

[Bob Swift [Bob Swift Atlassian Add-ons]]

Confluence Cloud is already at 6.0.0-OD-2016.07.2-0002. Perhaps your question is about when it will contain some of the new editor capabilities??? That is likely a couple of weeks away at least.
