Today it was discovered that a Canadian board game supplier posted the Clone Wars Armada expansions on their website. These Clone Wars expansions are the same 6 expansions that were leaked from a FFG Upcoming Products List by a European board game distributor a few months ago. The FFG Armada product codes match, which strongly supports their authenticity.
There's very little info; just the names of the expansions and their Armada product codes. The linked product pages don't contain any more information, there are no pictures are available ATM, and the prices are locked behind a retailer login requirement.
There are two small but significant differences between the two leaks. In the Canadian version, the Galactic Republic Fleet and Separatist Fleet products are referred to as "Starters" instead of "Fleet Expansions". That suggests they are faction-specific Starter Kits and contain essential accessories for Armada, i.e. dice, range tool, movement tool, tokens, and a damage deck. If that's the case, the Clone Wars Fleet Starters are presumably intended to help new players get into Armada, instead of requiring them to buy an Armada core set.
If that's the case, I expect there will also be Clone Wars Ship Expansions containing individual ships, like normal. They haven't been listed yet, but I think it's safe to assume they're coming. I can't imagine that FFG intends for existing players to buy Starter Kits that we don't need. Existing players are more likely to pre-order and buy the Clone Wars Armada products as soon as they hit the shelves, and if they sell out immediately, new players won't be able to get their hands on them. It makes more sense if FFG releases Clone Wars ship expansions for existing players to buy.
Perhaps FFG is deliberately withholding the product info for those CW ship expansions so the names of the Clone Wars ships don't leak prematurely.
