Wow, speaking of childish and immature comments...
It's the fan boys that make these forums what are otherwise a mature and non confrontational place to talk. Your reactions/behaviour to this is exactly the thing you justify for not releasing a roadmap. I've removed my comments that offended the fan boys so deeply.
Please name some examples of "all other businesses". You'll find pretty quickly that almost no other company, no matter of what kind, shares their roadmap beyond short-term major announcements. Ford doesn't release their roadmap for their car development, Apple doesn't share their roadmap for their devices, Pfizer doesn't share their roadmap for the new pharmaceuticals they plan to release, Blizzard does nothing to share their roadmap about their future plans for WoW .
1./ In terms of a roadmap, Frontier themselves have released videos and other media with their plans for the future, without going into semantics, a roadmap. Covered in my previous post above.
2./ Microsoft release their roadmap on the majority of their software including how long it will be supportable, deprecated or replaced with an alternative product;
3./ Starbound have released a roadmap, albeit high level;
4./ Adobe release roadmap's for much of their software;
5./ AvePoint, Nintex, K2 - among others have roadmap's for their products, it's quite common for small to medium businesses trying to secure investment;
6./ Star Citizen.
I don't know about cars and toasters but in digital business roadmap's are common. I have one for my own team.
I'm not suggesting a low level breakdown of upcoming functionality, just what are "we likely" to expect in the expansions we signed up for. You might not care or want to ask for fear of hurting Frontier's feelings, but many of us would "appreciate" (not demand) some information as to what is to come. It's not unreasonable to ask, but flaming people for asking just deters genuine questions from other players.
Anyway, if you have nothing to contribute to the OP subject please flame elsewhere.
