yeah :( I read somewhere that it will come back in a few weeks, it just got too close to the manga, so we'd have to wait aaages for episodes to be released :P but I know what you mean xD the epic battle between Natsu and SaberTooth's dragonslayers was awesome though :D I started watching some time last year, I watched 138 episodes in a week o.O then I read all the manga and got more into the manga because it's further ahead xD Natsu is going to kick the crap out of everything in the next issue and it's going to be awesome, I can just tell.
and yeah :( they'll almost certainly go back to Edolas at some point xD so there's hope ;)
