Oh well. I can have it and start combining for the IV's. That is the way I got some of them. Magic Guard Alakazam is my final piece in the team (and I really need it), so I'm okay having just the female Abra with the DW ability.
It's probably in about 5 weeks, if they opt to cycle through again instead of adding another 30 B&W/Unova episodes to the cycle. Each region has 5 episodes rotated out and another 5 added into the list each week.
Might not have the episode you're looking, though. If you want to start from the very beginning, the site is probably 2 months from cycling back to the beginning of Kanto for the Kanto episodes (which includes the Orange Islands arc). Looks like the first episode of the Johto saga is up this week, though, as are the first few episodes of the DP/Sinnoh saga. Hoenn is probably 2 to 4 weeks away from cycling back to the beginning.
