We're their types kept mysteriously hidden after their names and designs were revealed.
I don't recall mention of Lucario being Fighting/Steel until some time after it was revealed. Let me check Serebii's archives... --- Creator of Jay's Journey (see quote!) "It's not ten years old! Therefore, it sucks!" - Nostalgia whores everywhere
As I recall, Zoroark's type was announced as soon as it was revealed. Zoroark was first shown as a silhouette on Pokemon Sunday, as the first 5th Gen Pokemon. It and Zorua were both revealed in the next CoroCoro. --- "The difference between fiction and reality is that fiction has to make sense." -Tom Clancy
I remember how certain everybody was that Reshiram and Zekrom were Light-type and Dark-type respectively in the period between when their designs were first shown and when we were finally told that they were Dragon/Fire and Dragon/Electric respectively. --- My NIDOKING brings all the boys to the yard: http://goo.gl/ExAoe
