Wow, what a cynical way to approach things.
I'm sure those who pre-ordered are getting Nevada because at the time it was meant to be included, and they basically paid for it - at least that makes sense to me. At some point (this I know) it became obvious that Nevada required a whole lot of additional development time, enough that completing it for free after released was not something ED was willing to do (this one is a reasonable guess), especially considering that it includes new technologies - ie. a bit more than just terrain development, not that the terrain itself is simple/easy/fast.
I know plenty of people who are just fine with buying Nevada later on. By your own account on time spent on Black Shark, it might not end up that expensive anyway. You can complain all you want, but ED isn't a charity; they do this stuff for a living as well as passion for aviation. The guys at the top reassess plans and change them as any good businessman might do when required.
Oh really? Well than that sucks even MORE.
So I spent $50 for BS, while many waited for it show on DVD or Steam and got it for $40, but I got nothing extra for that. That was ok at the time, I didn't want to wait, I had to pay more for it. However, to date I have less than 90 hrs in it, so I've paid more than 50 cents per hour for it, while I know many people who have several times that amount and thus paid just pennies on the hour.
Now I'll still have to spend $60 to get A-10C, but because I bought it at the wrong time I'll get LESS? Sorry if I don't feel sanguine about it. Considering what proportion of their customer base likely preordered it vs waited like I did, it seems to me like maybe more than half won't wind up paying for it and just us stupid late comers will. In other words, they won't make that much by making us pay for it anyway, especially as many probably will skip it, so that makes it feel more like a penalty.
