I'm going to chime in, although some of my points may have been made by others...
It looks like I will be somewhat satisfied by the update. An extra tab is nice, and equipment packs = win.
As for the $9.99 for a tab, well, there are two things that effect this
1) A character slot is $9.99. You get 45 slots (not including heroes and such) plus the ability to farm for minis. Twice as much space, but slightly less convenient, although not so much more so.
2) A new account runs around $10 or so (I bought a few a while back). Much less convenient, but you get 45x4 slots, 40 chest panes, extra material storage, 4 more mini farmers, and extra ZKey accounts. Even if they decide that GWx2 is unacceptable, no problem; I got three computers on my desk.
Both of these scenarios do not take into account the upgrades to storage on them. Both character slots and mule accounts will become more efficient with the upgrade. The only advantage to the Xunlai chest being bigger is not having to swap characters or fire up mules as often.
My point; I think ANet simply missed the price point on this. $2.99, or even $4.99 might be a better price for this (if it was $2.99 a piece, or $9.99 for all of them, I would buy for all my accounts right now), and balance out the storage capacity vs. convenience equation. Maybe they'll change it, maybe they won't. I will hop on the free slot and see how it goes, and maybe buy one in the future, but I won't be rushing to spend $9.99 right away. I got mules for that. Until the money equation works better for me, that is how I see it.
So, /unsigned, not because I think they did it completely right, but because I think that supply and demand will bring the price into equilibrium if people play this one smart.
Now might be a good time to pick up a couple of extra accounts and take advantage of the free slot
