As far as Martial Power: wow! If the power cards are to be believed, that's 100 powers per class, which is more than what we've seen for them in the PHB. Hopefully that will not be too much feature creep ... I certainly hope there has been some SERIOUS playtesting, or we may find the original PHB much less useful for Martial characters.
For the rest: I'm surprised at the lack of products. I've been looking at the release schedule for the rest of this year and now into the next, and there's not a lot of products that I'm very interested in. The martial and arcane books are a given, as is the equipment guide, but the rest ... color me underwhelmed. I have to seriously question this new release strategy...does
WotC not want to sell as many products for
4E?
Still, I'll take quality over quantity, so hopefully these new releases will avoid the "Sword and Fist" splat effect...
