The main focus of the next update is localization support for Emerald Run. The supported languages will be French, German, Portuguese and Spanish. I'll expand to more languages in the future.
Also, there will be some improvement in the graphics shaders. iPad 2 shadow mode should be better. Another interesting tidbit is that doubling the shadow map resolution on iPad 2 does not really harm performance but yields much better results. Lower end armv7 devices should run a little better too.
