When will we see smooth terrain?

Its a question that's been asked ever since RDC West: When is smooth terrain coming?

Our first look at Smooth terrain was back during BLOXCast October, when we saw the new grass and best of all, the water. Smooth terrain was first made available to certain people on Gametest5 back in January. Developers like CloneTrooper1019 and TheAmazeman showcased it off. It was also shown off at RDC West and given a release time: Spring. Counting from today, there is about 43 days left until Summer in the Northern Hemisphere.

Last Friday, Clone made a tweet saying that smooth terrain would come this Wednesday. And it didn't. So when will this get released? Arseny Kapoulkine (zeuxcg) said that smooth terrain was almost finished  and that he was "waiting for iOS at the moment" back on Wednesday, which is probably why this feature didn't get released. So, my best guess is that this feature will get released in the next 1-2 weeks.
