The trailer for the English version has just hit. Here's my thoughts on the trailer:
The animation is absolutely beautiful, just what I'd expect from a Miyazaki film. I'll definitely be going to see this without question.
As for the voices:
Liam Neeson as Fujimoto: this is quite different from what I was expecting, but it sounded pretty fine to me. (Keep in mind I have not seen the Japanese version, so I have no preconceptions on how the characters should sound.)
Lisa: The one line I heard sounded a little monotone, but I hope that this is just one line. Still not a breaker.
Frankie Jonas as Sosuke: Better than I thought! Granted this was only one line, but it didn't sound lacking to me in any way. I don't have an overall opinion of the performance, but hopefully it'll be believable enough to assuage any naysayers (I think they'll hate on it either way).
Cate Blanchett as Granamamare: Very close in tone in Galadriel. Nice.
Noah Cyrus as Ponyo: Very difficult, because the only lines I've heard from her so far are giggles and some shouts. But they sounded fine to me. Again, I expect haters to dogpile on her either way, but what I heard did not sound like anything to scream about.
All in all, I think this is shaping up to be yet another terrific Disney-Ghibli dub. Of course, the rabid naysayers will hate it no matter what, but I haven't been disappointed in any of their dubs so far, and Ponyo seems to be another promising addition to the "family".
I'm looking forward to this.
