I think I fall somewhere in the middle here – I think Cocoa, GCD, 64-bit, GPU utilisation to name a few are an amazing feat for an update, but I think layered illustrator/pdf files should’ve ABSOLUTELY been added long time ago, especially since the PDF format has been established for and hardly unchanged in years. One can only hope it in the future update(s).
Also would love to see some real 3D but I think this will probably never happen, I guess we always have Cinema 4D for that..
