Being that most of those, if not all, are rumours, I'll take them with a grain of salt but if they do prove to be true, I must say that some of them disappoint me and a lot are actually good additions:
Disappointing:
- Bond levels. This might be a good thing if properly implemented, but it'll also probably mess up a lot of the Happiness only evolutions.
- Introduction of many Baby-level pokemon. While I enjoy older pokemon getting evos, Baby evos are pretty much useless in the grand scheme of things, other than collecting purpouses.
- The time travelling thing. Must first see how it'll be implemented, but a poor execution can potentially ruin the game.
Good additions:
- The Bond-Eye, Whistle and new 3D pokedex. More overall information in-game is always a good thing, as it makes the games much more interactive than they already are. And the ability to cure confusion without having to swap pokes is welcomed (and probably meta-game changer).
- Trainer levels. Makes a lot of sense actually, to also increase your skills as a trainer as you progress through the game.
- Fennekin being a Fire/Psychic type. Best-Fire-Starter-Final-Evo-Ever 
.
- Wireless Co-op.
