I don't really care if Go gets a Pokemon here or not, it matters very little and means even less when he does it. I've gone back to trying to ignore his captures as much as possible. Though, to be fair, the same applies to Ash's goal in that it matters very little and means basically nothing when he wins or loses.
As for Eusine, eh I won't be bothered that he's not here. His sole character trait is, "I want the legendary dogs also I wear a cape because I'm mysterious." I hope it's Pokemon Hunter J's sister, back to avenge her sister, but it's probably not. I miss Hunter J, she was a great recurring antagonist.
