Yes, that's right. Any unexplored land in the world will generate with all the new features of 1.7. Land which has already been explored/generated will mostly only have pre 1.7 features. Some things will be available everywhere, fishing for example would yield all types of fish no matter where you are in the world.
I am planning on wiping the nether, but I may not wipe it in the update to 1.7. I need to ensure that everyone is aware of the nether wipe, as not all read the forums. An in-game warning will come up indicating the date of the wipe, when I have sorted that out (and decided on a date)
The world generator changes in 1.7 change the location of generated strctures in the world, for most it does not really matter; I believe witch huts are the only ones in the normal world to be affected. A new saving system had been added in 1.6.3 to solve this problem by saving the location of existing structures, so they can continue to function in 1.7 and beyond. This new saving method took considerably longer to save than it did pre-1.6.3, and so I had to turn this off. I will be turning it back on soon, which will allow structures to be saved. If there are any structures you wish to be saved, you will need to visit it (load the chunks) before we update to 1.7. If the structure is not loaded in this time, it will not make the transition to 1.7 and will cease to spawn witches, etc. I'll post here again when I turn it on. You can expect lag during world saves whilst this is turned on.
