Yeah, the community did wonders for the Xperia Play. I mean, there are people still buying and using this phone today. I honestly, just left my play this year for the Much W1.
I think that the pitfalls that the W3D will have are small and can be easily fixed if left to the community. Updates to Lollipop, Tincore intergration into the Rom, overclocking (I mean, we got 8 cores, lol), maybe even the issue with newer apps not syncing like on the Much W1.
