In a surprising update (not really, more-so late), Pokemon-Card.com have updated on the DPt4 situation presenting us with new cards not seen before, including the last three Arceus cards originally left unrevealed. They also unveiled some of the cards due out in the Random Packs this August. Confirmed now is that the Random Pack series will have 22 cards. Two new victory medals were unveiled along with a Mewtwo and Heatran promo (amongst many others). All in all, a huge update, all broken up into sections for your convenience.
Pokemon Battle Tour 2009A new battle tour is beginning July 11th and running through until September 6th. They nicely showed off Gengar Lv.X on their images, with two coins being given away at the event. They also
inadvertently showcased the entire set of DPt4 in squint-o-vision but you can see what you're looking for if you look hard enough.
Commercials:Pokemon-Card.com revealed a teaser CM for Dawn of Arceus tonight, including a special introduction video to how the Arceus cards work in the game. Take a look at them at the site
here or check them out below:

DPt4 Dawn of Arceus, DPt4 ArceusLV.X Grass&Fire Deck, DPt4 ArceusLV.X Psychic&Thunder Deck:The final four Arceus cards were unveiled tonight, to go with the fact they're fully revealed in the new CM and the Introduction video.
Movie Commemoration 2009 Random Packs:Officially announced today on the website, Pokemon-Card showcased a few of the cards featured in the deck. As suspected, SP pokemon for the movie characters are a factor. Instead of having many confusing titles, they have used M as the SP name symbol, standing for movie. It's a stylize Pikachu tail, which is a nod to Pikachu Project. A new energy illustration has been done for this set. Contrary to the initial release date issued by many online stores for pre-orders, the packs are due out on the 8th of July also. The set features 22 cards, all of which were revealed today. Take a look at the set below:
