Well spotted! It does look like 魂.
It's a cool cover overall but I think something is missing... Somehow it doesn't have that Gintama feel to it.
Anyway, about the release specs: this first volume includes two DVDs with the first 13 episodes and has no English dubs. Even though I always prefer the original Japanese version, I kinda wanted to see how would they manage to be as funny as the original dubbing cas.
Also, for everyone that's hoping to buy this collection, save your allowance to June, the second DVD is due to the 29th, retail price $49.98, though you probably will get a better price from Amazon or Best Buy ; )
