The Queen is alive (finally confirmed?)

I was playing one of my alts the other day and came across this flavor text from step 8 of The Taken War: Petra quest. It reads as followed: [quote]"I leave this in our usual location. Knowing these files have not been touched since that day, I doubt this will be of assistance. But just in case... Please Mara, reach out. Contact Petra, contact me. If you can." -Audio file, Royal data vault, timestamp four days after the battle at Saturn.[/quote]The way this is narrated, I believe this is a message from Uldren, The Queen's brother. Thoughts?
