Just like you guys I'm really confused with the anime right now!! The league is suppose to start in three months in real time that's november...but if one episode represent one day in the anime we may have 90 episodes to go (Maybe, just a theory)!! But let's see there are still things not advertised from the games:
1. Team Plasma (IF they appear they make take a couple of episodes)
2. Black City / White forest (Introduce Banjirou)
3.Aspertia City
4.Floccesy Town
5.Yamaji Town
6.Relic Castle and relic path
7.Lostlorn Forest
8.Mistralton Cave
9.Dragonspiral Tower
10.Moor of Icirrus
11.Challenger's Cave
12.Royal Unova
13.Giant Chasm
14.P2 Laboratory
15.Unity Tower (A tournament here, could be nice)
16.Floccesy Ranch
17.Oath Woods
18.Virbank Industrial Complex
19.Pokéstar Studios (More movies could be nice...That means more Luke and Zorua ;D)
20.Pokémon World Tournament (In still think their are more branch of the world tournament..senior cup, allstar cup, master cup)
21.Rebirth Mountain
22.Underground Ruins
23.Stranger House
24.Seaside Cave
25.Clay Road
26. Opelucid City and Drayden
27. the elite four could also be introduce
28. NPC like Tetsu, Ruri, Sabrina, Morimoto, Looker could also be introduce
29. Half the unova dex mon haven't debuted yet!!
The bridges and tunnels may also have a cameo or something!! Also some characters needs more development Dragonite to listen and control himself, Scraggy mastering focus blast aim, Krookodile not lose his focus when he lose the sunglasses, Iris getting over her ice fear, Axew controlling outrage, Emolga learn to battle and to stop using charm to tricks male pokemon, Cilan catching a new mon and taking the an connoisseur test , Bianca to get more stronger and so those Burgundy, Trip to battle Cynthia and Georgia to battle Drayden and finally more Don tournament in which finally Ash wins one!!
I know that some of this places won't appear in the anime but it could help extend the anime to september 2013.
