Normally, dub titles aren't interesting news. If it was entirely new to us, we might make guesses about Ash trying to get a legendary and that Team Magma will be involved somehow. As it is, we know that this is Part one of the two-part "Groudon vs. Kyogre" battle with Team Aqua and Team Magma both also in battle to boot!
But what is interesting is that we can see that 4Kids are clearly making an effort by having more difference in the title than the numbered part.
