I know that, but the impression given by the devblogs is that they ran out of time to go beyond just the simple features. They way they've worded some things suggests that it released before they wanted to, and the patches are now bringing it up to the standard it should have been on release.
They've said in other devblogs that they know they didn't go far enough with some things and it's lacking. It seems like it's less "We can do it better now" and more "We didn't get time to do it right in the first place" with some of these things.
I'd have to agree with you.
I can imagine that it may have been a case of a deadline they had to hit maybe for the IPO, or maybe just budget constraints meant they needed to get it out of the oven and get some cash coming in.
I've not played in a while (wedding, month long honeymoon, work) but I'll be jumping back in with the DLC.
