this 2.0 editor was started to be developed in last summer, and will be ready for the next summer as a latest date I think. finally we can compare it to the new WED... the engine behind remains the same similarly to A8. until that you can use the 1.0 editor for free, which is okay for a one person development, and can keep it until you want to make free games. its licencing will be stopped after 2.0 released.
for easier programming, you can check its built in script editor, which is in the current editor too. you have to install VC++2008EE or 2010EE before for free, it is linked to it in the background, but much easier to program: it uses a script language like a mixture of C++ an C#. no need to deal with header includes, has its own memory containers managing allocation, member searching and maintenance, easier class and struct definitions, using . instead of -> etc.
