The touring blockchain works. My understanding is the gui official release is close.
The move to POS and scalability are the next dragons to be slain. They want to be able to handle visa level transaction volumes which is yet to be determined. Homestead is the official "it's safe for moons" release. Serenity (I believe) is the "it's scalable and ready for prime time" release.
at this point it's a wait and see, just hope they're not going to drags this on forever. i see there is no possible way for it, just too many obstacle and bottleneck. at visa level the eth blockchain would collecting TBs and TBs of data daily. i wouldn't invest in this coin by the way, to me it's not much of different with other coin because i still think this smart contracts is useless plus it's not for consumer level and the dapp going to collecting terabyte and terabyte daily if it even possible for scalability
