This one isn't really deserving enough to save for Wednesday, so thought I'd just let you all know it's out now. Basically, it's the new keyboard from the L version of Android.
It looks better than the current one, it seems to be smoother in normal use and that's all I've noticed so far. I like being on the cutting edge though, so I'll be using it until L drops eventually for all devices come fall.
Give it a go if you're interested.
