Yeah, Japan is supposed to get a release pretty soon but it's by Toei (same company that has the Sailor Moon masters) and they've said they're just going to upscale stuff so it won't be actual HD (same as Sailor Moon).
Transformers: Prime was dreadfully boring. Very pretty to look at though.
Animated (and Beast Wars at this point) had the opposite problem. AMAZING writing that has to struggle through some rough visuals.
You rarely find new DIsney stuff cheaper than when it's first released.
I got Iron Man 3 for $24.99 day of release and I don't think it has been cheaper since then.
