Per today's newsletter:
"For next week's Open Beta update, we plan new Hornet features and fixes like the Joint Helmet Mounted Cueing System (JHMCS), FPAS page, laser Maverick, and corrected air-to-air radar B-sweep."
Note the use of the word "plan" - to quote Rabbie Burns: "The best laid plans o' mice an' men gang aft agley!"
Things go wrong, things take longer than expected - until you see it in a changelog, expect things to slip.
