Information regarding the english version of the Pokemon White/Black 2 guidebooks has been posted on Amazon.com. As with the first release there is also a collector's edition, the only difference that appears in the collector's edition is an interview with Junichi Masuda. Both will be released on October 7th. Also neither mentions any sort of regional dex, which means they're probably saving it for the big national pokedex that will include the hidden abilities.
