Well it's an interesting thing. As you can't come back to the normal world without dying which means you can't bring anything back it would be pointless to have special blocks or items there. I think The End will contain challenges instead like bosses or so, unlocking content in the normal world too. There's huge potential in this and will most certainly be taken advantage of.
The only thing that makes me feel bad is the deadline. According to the current state of the game it's kind of pointless to create deadlines and - again - rush things just to be able to call it "1.0". They rather postpone the full game release until they REALLY finish adding content and bugfixes. There are still no bosses and much more bugs than what a 30 day bugfixing could cover. But well... we'll see.
i hope they make the nether and the end as compelling as scokeev9's nethercraft mod made the nether.
