I want this game so bad. But I'm still a little worried about the battle speed tho, it feels a little slower than the first Xenoblade, I don't know, I can't tell exactly what it is but it felt odd when watching the gameplay from E3.
It's not especially.
It "feels" that way because now you have to chose between moving and auto attacking. There's more strategy in positioning and timing of attacks.
Then, you need to charge arts with auto attacks whichare not available at the beginning of battle, also making it look like slower.
Not to mention they almost only play with Rex which is equiped with 3 slow weapons.
Watch Nia, she's much faster.
The last points can change depending on your skills/arts (most likely), character, weapon and so on.
I've said it before, but best case scenario is we get XBC and XBX as alternating releases. They fulfill two very different needs.
It's not best case I think, rather it's a very realistic scenario.
In any case I don't see them developing numbered Xenoblade each after the other with nothing inbetween.
