It was never said that it will stay cpu only, actually it gives the chance to do some cpu mining before gpu moves in.
(and tbh, there is no cpu only coin... even though supcoin was pretty close to that... but since the dev stated everywhere it was only a test coin

)
I agree, I'm just saying that as soon a GPU miner will be release, that coin value will drop to nothing and will die.
The only "good" CPU coin only is XMG, but I'm sure you already know that...
