As far as I understand, a serious benefit of Processing was that it used it's own P2D renderer instead of Java2D which is slow and much less versatile. Now I have read that the P2D and P3D renderers are going away with Processing 2.0!!!

Now I have this question - does it mean that developing 2D sketches in Processing would be not so fun anymore? Will they get slower in graphics? Or will I have to use OpenGL for everything instead of P2D? I made a heavy use of P2D so what would I want to do then? Would I just switch to the OpenGL renderer entirely? Is this change a loss or is it a gain?
