Sorry, I'm going to be that guy - it's May 1st! How's the timetable looking for the May 2019 release of PBIRS?
I have time scheduled out for a QA upgrade by the end of May, and then the Prod upgrade in June if QA goes well, so any info you can share about the release looking on (or off) track would be very helpful. Thanks!
There are still a couple of weeks left in May... The Report Server PM made a cryptic comment on twitter about it being time to prepare a video this weekend so I'd hope this is in relation to the May release. I'd also just keep an eye on the Power BI blog https://powerbi.microsoft.com/en-us/blog/ they are unlikely to announce something on this forum that has not already been officially announced there.
I was almost "that guy" too, but decided to be patient for a couple of weeks. And you should not feel the need to apologize, RS updates have historically been delayed, not to mention the fact that upcoming RS features are not even identified on the roadmap.
