Posted this on another thread but it occured to me that this hasn't occured to a lot of people: I certainly didn't notice it until about 20 minutes ago when I made a graph to illustrate the exact opposite of what I'm about to say.
The Y-axis is releases that quarter.
We all know releases have sped up and a lot. Most of us assume FFG knows it's found a goldmine and is releasing more and more and more to get maximum money out of it and that it's getting to the point now where it's hard to keep up. I'm going to present an alternate case, that FFG has a regular X-wing release schedule, that that hasn't changed since the early waves, and the reason we're getting so much stuff at once is because that schedule fell to bits.
If you look at the SKUs they don't match the release order at all. Red are the ones that break the sequence.
SWX 01: Core
SWX 02-05: Wave 1: X-wing, TIE fighter, Y-wing TIE advanced
SWX 06-09: Wave 2: Slave I, Millenium Falcon, A-wing, TIE interceptor
SWX 11: Rebel Transport
SWX 12-15: Wave 3: Lambda-class Shuttle, HWK-290, B-wing, TIE bomber
SWX 16-19: Wave 4: TIE defender, TIE phantom, Z-95 Headhunter, E-wingSWX 20: The board tiles
SWX 21: Imperial Aces
SWX 22: Tantive IV
SWX 23-24: Wave 5: Decimator, YT-2400
SWX 25-28: Wave 6: Most Wanted, M3-A Interceptor, StarViper, IG-2000
SWX29: Rebel Aces
I'll now reorder these into Release Order.
SWX 01: Core
SWX 02-05: Wave 1: X-wing, TIE fighter, Y-wing TIE advanced
SWX 06-09: Wave 2: Slave I, Millenium Falcon, A-wing, TIE interceptor
SWX 12-15: Wave 3: Lambda-class Shuttle, HWK-290, B-wing, TIE bomber
SWX 21: Imperial Aces
SWX 11: Rebel Transport
SWX 22: Tantive IV
SWX 16-19: Wave 4: TIE defender, TIE phantom, Z-95 Headhunter, E-wing
SWX 23-24: Wave 5: Decimator, YT-2400
SWX29: Rebel Aces
SWX 25-28: Wave 6: Most Wanted, M3-A Interceptor, StarViper, IG-2000
What does this mean? It means the Transport started design before Wave 3. If they released in order of conception we'd have had it before we had B-wings. Why was it held back? Any number of reasons. What am I attempting to illustrate? That sometimes things take longer to design and balance than anticipated.
Galaxy Tiles, SKU20, was announced April 2013, soon after Wave 2. That means Wave 4 could have beginnings as far back as six months after the game was first released two years ago. What am I trying to prove? That a lot of the stuff we have now has been in development for a long time.
Look back at my graph. Something look wrong? For those not looking at the quarter numbers and just following the Wave 1, Wave 2, Wave 3 spikes, it looks like Wave 4 only has one ship. That's because that's Imperial Aces. Now I make my crazy assertion.
I'm pretty confident that Wave 4 was originally planned for Q1: it should have come out in February when Imperial Aces did.
Why was it delayed? Probably the same reason our friend from further up this post, Rebel Transport, was: it took longer than anticipated to balance it or get Licensing to approve it (TIE phantom's kinda obscure) or something.
Look back at the graph of the release schedule. Now, what would it look like if everything had gone to plan? If the Rebel Transport was released after Wave 2, Wave 6 is released in Q1 of next year and if Wave 4 came out on time?
Our sudden increase in releases in the second half of this year is mostly gone. This is a steady but regular and hardly excessive release schedule.
It's not much of a stretch to push this a little further to get what I think was FFG's plan. I'm going to tweak the release of Imperial Aces a quarter backward and Rebel Aces a quarter forward: one quarter of drift between planned release and actual release is hardly unreasonable.

Bearing in mind that Q3 14 is only that short because Wave 5 only has two ships, who would complain if FFG released like that? A wave every six months and a misc expansion between them. I'm very confident this was the plan. With the graph like this, it goes Wave, Huge, Wave, Acepack, Wave, Huge, Wave, Acepack, Wave.
Of course, no plan survives contact with the enemy. They got Scum ready for their big reveal at GenCon and seeing as it was ready went for Christmas release as any wise business does, Wave 4 was a quarter late and the Transport even more so.
This isn't FFG stepping up the release schedule, it's all the stuff they planned to release earlier turning up with the stuff they planned to release now. It's two buses turning up at once syndrome: there's only two now because one of them is 30 minutes late.
Thoughts?
