Nether Updates!
Jeb recently revealed a new spoiler screenshot of the nether! We can clearly see some sort of nether-brick bridges spanning over the massive lava lakes so prevalent in the Nether. This definitely bodes well for Nether travel, making the trip across massive distances much safer! ...that is, if they generate everywhere! Where do they spawn? Are they a part of a larger structure elsewhere? You'll just have to wait and see!
Unfortunately it seems that Mojang won't even acknowledge the low FPS problem (4-7 FPS on 1.8), so I guess I just don't really care anymore.
A new block or distorted coloration of the picture.
but i dont think, that this is nether brick...
for me it look more like a sort of nether wood planks.
