Yes, they announced it because LEP owners were voicing their concerns, so they hoped to ease those concerns by saying what they did, but now it's opened another can of worms...
However, I completely understand what you're saying, Frontier have been very tight lipped the last year or two and I will admit I did expect them to show more. But, I kinda guessed there was going to be paid for content besides the free stuff, so I wasn't worried in that sense.
I don't see any can of worms myself. There's a paid for DLC of some sort aimed at end of next year. I have no issue not knowing what it is, or indeed if that date slips. It simply lets me know there is some other development of note going on, and not just "Beyond" which to me seemed a little less than I would have hoped for it that's all that was going on.
As I said, just that little little extra bit of information about next years road map, has made a significant difference to my view of next year. Hence me suggesting it should have been included (at the weekend).
