probably not the latest game in the Gundam Battle series (Gundam Battle Universe screen above), which already have four PSP games so far. The answer will probably in the upcoming issue of Weekly Famitsu this week.
Update: This is more or less confirmed by another online retailer Rakuten who says this is currently under development by the Gundam Battle team. It appears to be a team-based action game with maps that change in real-time. Among the anime to be included are Mobile Suit Gundam SEED Destiny and Mobile Suit Gundam 00, MS count is more than 300 units and the amount of characters included is said to be 100. Customization plays a big part on the game too with features to create your own character.
