Other versions have their updates follow the updates of the PC. I don't think Mojang would have all the textures different based on the version. Yes, this update is for PC, but it will indeed transfer to other versions.
Stop using the "Just use a resource pack." argument. It is completely invalid. What about people that play on versions that you can't get texture packs or it is very hard to get them? Also, when something is default, it changes the way players see things. So far they don't look too different from the original textures, and I actually like some of them.
I just hope this doesn't turn into what happened when Mojang changed the wool colors. I wouldn't have cared if they made the new concrete all bright with different colors like that. But to change the color palate, of a common block that people use for building, was a really imbecilic move on Mojang's part. Some of the blocks, like I mentioned earlier in the post, should get a little bit of updating. I would actually like it if they toned down the contrast on the wooden plank, like the latest update for the wooden planks. I just hope Jasper does a good job.
Side Note: What do you guys think Notch thinks about the texture change?
Agreed. Now there are people saying that there needs to be a texture change, but that's only because Mojang/jeb_ said it. It's like with the 1.9 combat update. I'm not saying that combat didn't need to be changed, but there were a lot of people that agreed with Mojang on combat when not really many people complained before.
Good to see I'm not alone on the diorite thing. I think diorite looks pretty gross right now; I would prefer if it were just a white andesite. I think the wooden planks look okay but the logs look a little blurry.
