Finally I sincerely hope that they use OpenGL and not DirectX as base for their 3D graphics - this should reduce development costs for the platform ports.
Mmm. OpenGL also got a lot better and easier to use the last years. 10 years ago I understood why people rather used DirectX. It was easier and you almost always got better performance. I still think DX is easier to use then OGL (even though you now also has framworks as OGRE that really helps when using OGL)... but the performance is more or less identical these days. And as you point out, it is much more portable.
There is also the possibility that FD has their own 3D framework... In that case they will have to port their entire 3D framework. And that won't come cheap.
I don't dare to make predictions if people will stop using PC completely by replacing them with a tablet even though most applications are available for all platforms.
I thought tablet was a PC form factor... such as notebook, desktop, tower, laptop and so on... I have a hard time seeing people replacing their PCs, such as windows, macos, android, ios and Commodore Basic computers with tablets that isn't PCs. Would that be that they replace their PC with a tablet server or similar?
Yes... I'm ranting a little bit
... But working as a computer professional I believe that it is quite important to separate computer form factors and computer usage.
Form factors is the exterior of the computer. This hasn't anything to do with it's usage. And both usage and form factors isn't singletons. A computer can be both a server and a personal computer at the same time. But for example a router is most often only a server... even though many can be used as personal computers. And when talking about form factors you have computers that can be both laptops and tablet... most often called convertible or hybrid.
If you break it down, most modern phones are PC tablets. They are tablet form factor (even if they are really small tablet form factors). The most OS on them, such as Android, iOS, WP8 or Symbian, is primarily designed to be used for personal use (even if most of them can run server software), so they are personal computers. Hence; Personal Computer in Tablet form factor.
(And just because I know that people will ask this; Yes. If you install a server software on your small PC tablet phone (or as we usually say; smartphone) it is also a server... so... small PC/server tablet phone...)
