Regarding Autofire and the lack of change in this week's update, Cyril brought up an interesting point over on the d20 Radio Forums.
What if the change to Linked (2 Advantage per extra hit) is a test bed to see if the same update would work for Autofire? If so, the devs may simply want to see if that works, and if so will proceed to update Autofire with that change in the next update.
As for the spacing out of updates… it could very well be that from the devs' perspective, there may not be that much more that needs updating. Also, maybe it's less "more time to test this week's updates," but "more time to test all the various updates in general." After all, it'll likely take more than a week to do more than just eyeball the cost changes to specializations and skills from the prior update.

Dice math is a ship that has largely sailed, as the orders for the Beginner's Box dice sets have in all likelyhood been sent and production begun. The most they can probably do is tweak it a bit, but again it could simply be that unlike a few of the more vocal posters here, FFG simply doesn't see it as an issue; again, paradigm shift away from what 40+ years of tabletop gaming has reinforced, with more of an emphasis on "group dynamics" than "solitary spotlight" when it comes to the results of one's roll.
Frankly there are aspects of the game and updates that I'm not all that thrilled about (the low defautl starting credits, which almost requires a PC to take additional Obligation, the costs of some of the Upgrades for Force Powers and the revision of the Sense power tree in the Week 2 Update in regards to the Duration talent), but at the end of the day, it's FFG's call as to what needs to get fixed and what is working exactly as intended when the game was written. If we don't like what they're doing, we as the consumers have the rather easy option to simply not buy the final product when it comes out, and instead pursue other venues for our Star Wars gaming pleasure, of which there are many.
