Overall I'm happy. I love Wishes but I've seen it on every trip I've been on - I've never known MK without Wishes. I'm ready for something new! I'll miss it and feel nostalgic about it but I have plenty of recordings of it. If Wishes never changed everyone would start complaining that it was stale, that Disney doesn't try or want to spend the money. I think this is one of the few ways Disney actually acknowledges its repeat visitors and gets them to come back.
The only thing that makes me nervous is that if RoL was so poorly executed, is that going to become a pattern for Disney? Is this show going to be a step down from Wishes? I hope not, maybe RoL crashed and burned because they had a lot of people focusing on this, who knows? I look forward to hearing the reviews and seeing it for myself.
