Konami plans to release two new boosters for the Yu-Gi-Oh! TCG this spring: Yu-Gi-Oh! Premium Gold will release on March 28, and Yu-Gi-Oh! Dragons of Legend will release on April 25th.
The Premium Gold booster takes the best cards from the past Gold Series sets and adds new cards to the mix, as well as introducing the new “Gold Secret” card rarity.
"Gold Rare" cards, which "enshrine" the cards in a gold color (gold card frames, gold art boxes frames, gold text box frames, card names and even gold level stars for Monster cards), have been available in a number of hobby exclusive Gold products in the past (see, most recently, "'YGO Gold Series' Cards Announced").  The new "Gold Secrets" cards include all those upgrades and add a Secret Rare Card’s textured foil pattern on top of it. Each 5-card “Premium Gold” mini-pack contains two "Gold Secrets" (either a brand new card, or one of the Legendary Gold Cards from the original Yu-Gi-Oh!  series).  Each mini-pack also contains three standard "Gold Rares" (one card a never-before released  Gold Rare, plus two past "Gold Series" cards).
Each Premium Gold box contains three mini-packs (for a total of 15 cards: six "Gold Secrets" and nine "Gold Rares"). MSRP is set at $14.99.
The final name and release date are still tentative, but Konami has also posted information on the Dragons of Legend booster, which it plans to release in April.
Dragons of Legend will include dozens of the most popular and fan-requested cards that have been used by duelists on the shows (including the original Yu-Gi-Oh! TV series, Yu-Gi-Oh! GX, Yu-Gi-Oh! 5D’s, and Yu-Gi-Oh! Zexal)--all in print for the first time ever.  The 5-card packs will contain one “Secret Rare” and four “Super Rare” cards.  MSRP for the packs is $3.99.
The Premium Gold booster will follow the Cyber Dragon Revolution Structure Deck and the Star Pack 2 which release in February (see "'Yu-Gi-Oh!' Structure Deck, Star Pack").
