Japan has a set coming out soon called Golden Sky, Silvery Sea, which contains the GS starter EX's (G8r, Meganium, Typh) as well as all 28 Unown (!?). Speed Deoxys was a Japanese promotional card, as were quite a few of the Deoxys cards released in EX: Deoxys.
Right now, we really don't know what will be in our set called EX: Emerald, which IS the OFFICIAL NAME of the set. It could either be the cards from the Quick Construction Packs, which were released as a semi-promotional set in Japan about a month before DX was released in America and contained almost all the broken cards in the format, including Candy and TV Rep; or it could be Golden Sky, Silvery Sea; or it could be a combination of the two. Also, POP series 2 packs are coming out soon, and we have no idea what will be in those packs.
That's all that I know for now. Cya.
