This is great news but you didn't answer one of the very questions that you brought up?
When is Service Pack 1 coming?
For that matter, you initially promised quarterly releases for cumulative updates to correct many of the bugs present in Exchange 2013. After the last snafu, you have not only passed that schedule but have gone dark as to when we can expect the next cu release. Will you return to quarterly CU releases or will they be released as before (infrequently)?
There are some very clear issues with on-premises Exchange 2013 such as the issue with transparent OWA rendering to existing E2K10 users. This is an example of an issue that doesn't affect the cloud but on-premises users. It is ok that MS is focusing on the cloud but this seems to be not in conjunction but to the exclusion of on-premises users. The trickle down effect only seems to apply when the cloud and on-premises share the same issues or features. In fact, when CU2 was released there weren't even any accompanying notes as to what was even being fixed.
So your post is well-intentioned and a good direction but doesn't even scratch the surface of the pain the on-premises users are facing when promoting your product.
