Yes

We usually don't add a category unless there are people actually running it so we don't have excessive numbers of categories. When the Zombie hover glitch was discovered there was still a desire from multiple top runners to continue doing runs without this glitch, so the split was made there, but there has not been anything similar for NG+ so far.

Text is exactly the same. The voice packs actually do affect the speed a little bit in some places, it seems JP voices might be slightly slower but its pretty negligible and hard to tell for sure.
