I didn't get to hit with Dynacore 315 that long but it felt like a stiffer 315ltd. It was nice, reminded me of a AeroPro almost. I am a bit confused what you are planning? You like the Dynacore315 enough that you are considering a second one, but are concerned there's a better one coming out (or maybe like Irvin mentioned with the new eyelets)? I mean if you need a second racquet in general because you are breaking strings in matches or love strings that go dead fast then you should just get the second one cause I don't think another generation of 315 will be out for a while. Do you know what I mean? If you need a second racquet you probably should just buy it but if you don't need it then you could wait to see.
