Oh, I can post something that is more "nothing" than your "nothing".
This is the code of Minecraft PE 0.3.0, reinterpreted as abstract art by loading it into an image editor as raw image data and then saved as a .jpg.
I dunno, I'm pretty sure if I stare at that long enough, I could pull more 0.4.0 spoilers out of it than from the crap images posted here...
Did ya see, there's a 3rd pic in the OP now...a bone-stock terrain.png from 0.3.0. Yep, it "leaked" right out of the OP's apk. How fascinating!!
Guys, this is not that bad of a find. This just tells us that there may be rails in the next update.
Except that...no...it doesn't. It tells us nothing; that's what we've been going on about.
As I said before, that pic with the rail "is an old pic of MATTIS (the crafting GUI) when it was still in development." That pic was released on Twitter months ago, while we were all still playing 0.2.2, and couldn't wait for 0.3.0. Just like everything else in that image, the rail was a placeholder, just to show off the tabbed interface. It has nothing to do with when rails are actually being added.
I want rails just as much as everyone else, but all these crazy jumps to false conclusions do nothing but get everyone all excited for something that may or may not be coming. And when people get excited around here, they start spamming the forums with threads like, "when is the update?", "is the update out yet?", "the update is coming soon!!", "rails confirmed in the update!!". It's no fun for anyone during that time...

No, that's all the items in the PC version, as of a few updates ago. Pocket Edition uses pretty much the same graphics files as the full game, so they're not really much of an indication of what is actually implemented in PE.
The first one is an old pic of MATTIS (the crafting GUI) when it was still in development.
The second one is a gui_blocks.png for some texture pack.
This is truly "nothing" at its finest.
Secondly, the clouds were from assets/gui/default_world.png in a Minecraft PE 0.3.0 APK, and is identical to pack.png from the desktop Minecraft.jar. Mojang was too lazy to take a different screenshot.
