FFG realized that The BIG Boys play this game and so they decided to not play tickle-tail cuties about just showing stuff ASAP, which is why we got the made up BS W3 & W4 which I simply call Wave THOR.
That happened due to some issues with the new factories. From now on I think we can expect an entire wave with each ship being fully previewed in it's turn.
Not quite.
Wave 3 is clearly a panic response. I have a strong suspicion Wave 4 was supposed to be out months ago.
Wave 3 uses painted models from the Rebellion board game. With the various production delays we are aware of and guessing at in Wave 4, it was probably seen as a fortuitous coincidence that both ships were already being produced. It meant that all they had to do was design cards and game mechanics, which could be done almost anywhere.
Wave 4 is about to hit shelves a full year after Wave 2 was intended to be in stores. The addition of Wave 3 was clearly a stop gap measure taken when they realized that Wave 4 would be delayed by such a significant period. And frankly I'm glad for it. Despite appearances, wave 3 is likely to have a much greater impact on fleet design than wave 4.
