The fact that the League is starting by next month tells me that we're going to see another saga after the League is over; I can't recall any league lasting more than roughly 3 months, which would leave us with a solid half a year until Gen VI. At this point, I'd say our best bet is another World Tournament. It doesn't require another long-winded schlepp like the BF did, as there are no new leaders for Satoshi to hunt down. Alternatively, the writers could resolve to give us another schlepp in the form of Satoshi hunting down the Four Emperors and battling them one by one. Or they could have Satoshi win this PWT and be able to also battle the Four Emperors. At this point, I certainly wouldn't rule out either another PWT or a Four Emperors scenario. (or both) Either way, we have seven months following the League; hell, seeing as though Gen V is set to be a year shorter than the last two generations, I wouldn't rule out the possibility of Gen VI being released next November like Gen III was, in which we would have nine months post-league. Either way, there's certainly a sufficient amount of time for Best Wishes to give us a final year that at least somewhat makes up for some of their earlier disappointments.
