My reading of all this is that in fact TEPCO's roadmap for control of the site is becoming increasingly unlikely, but I don't want to be alarmist and I know there are a lot of very technically savvy people on this site, so:

Note that the container they were using to hold the very highly radioactive water they were trying to pump out of the basements and trenches is itself leaking, and it's not a small leak. Most of us know from household experiences that leaks only grow worse over time. They anticipate that they will have difficulty plugging the leak because of the high radioactivity levels of the water that's leaking.
Plus, the reason they even found this in the first place was that they checked the water level in the container because they needed to pump a whole lot more out, and they thought it was just about full.
The plan to get in there and work on these reactors depends on clearing out most of the water from the basements.
So I don't know where they really are, but as far as I can figure it, they are getting further from control at this time. An IAEA team went over this week. Perhaps they had some helpful advice, like "Next time, check for leaks BEFORE you pump the very radioactive water in."
There was another fire at Fukushima Daini (different plant!!) on the 27th:

Here's another site where a lot of TEPCO releases are perhaps better organized for reading:
