I have been waiting for this for a long time. I have license for S2 and it is a great looking engine. S2 looks fantastic for lighting but A7 is really growing on me.

With Mysty Moods for Lite C and IntenseX AI it is hard to beat that to help make a great game. A7 has some great looking shaders and water shader. I can not believe what Loopix has done with Mysty Moods. And I like using WED.
