We'd all love the original Japanese versions, but I honestly never expected Uni to get them. I'm still giddy with the prospect of these new releases because:
-I genuinely love the US versions of both, KK vs. G mostly for nostalgic reasons (and the pacing is slightly improved), and KKE is a legitimately great one (and 2/5th of the cast speaking English anyway!).
-Universal's versions are in better shape than their Japanese counterparts! Even if you're a sub only traditionalist if you want to pop in a disc and see Godzilla fall into the fiery, poison gas pit or King Kong fight Gorosaurus in the best quality you'll want these discs. The DVDs look great so I imagine these will only look better.
