So there is a blog post up on Unity3d.com showing what’s coming down the pipeline. There’s some pretty interesting stuff on there. Apparently Unity 3.4 is at the release candidate stage and there are a few major announcements. Terrain support in iOS and Android is a biggy, execution order on scripts, procedural texture support and 2-3x improvement in skinning speed are all very nice new features.
The post goes on to describe what is in the upcoming 3.5 release, with tons of new features but perhaps the most interesting to me are the new UI framework, pathfinding and LoD support. Some really interesting stuff coming up, I highly recommend you check out the full post.
