Minecraft PS4 Nether and End?

Hi. I play Minecraft on a ps4 and would like to know…

1. When will I get the Nether update? (The one where new biomes and mobs are coming)

2. Can i reset the nether or end in my survival world to loot everything again? I know that you could do that in older versions under Settings.

1. If the version for the Bedrock is released (maybe earlier than the Java version, maybe later), kekner knows that.

2. Not that I know of. If it was earlier try it, but I've never heard of it.
