From the last PI's Perspective:
"Since I wrote you in early September, our ground team has been a lot busier than our spacecraft has, since they never hibernate. In addition to planning both the just-completed November wake-up and the upcoming 10-day January (2010) wake-up, they’ve also completed all but a few final details of the nine-day, Pluto-closest-approach encounter command load for 2015 and verified this command load on the spacecraft simulators at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md. Our ground team has also been hard at work planning next summer’s Active Checkout (ACO), which will run from late May to early July.
The 2010 ACO is our fourth of the mission, so it’s called ACO-4. Unlike ACO-3, which was very light on activity (to give our ground team more time to work on Pluto encounter planning), ACO-4 will be chockablock with scheduled activities. Among these will be a complete spacecraft and instrument checkout; instrument calibrations, to look for changes since our last set of calibrations in 2008; a trajectory correction maneuver, our first since 2007; a little cruise science focusing on the interplanetary environment and Uranus and Neptune imaging; more fault-protection software upgrades; some tests associated with activities we’ll be conducting at Pluto; and our first-ever full length encounter mode test on the spacecraft.
And just in case you think the ground team still doesn’t have enough to do, they have also begun the detailed planning of the final few weeks of our approach to Pluto that precedes the nine-day close encounter period they’ve already planned out. All of this, mind you, by a team that is about 10 times smaller than the venerable Voyager team when its Uranus and Neptune flybys were planned in the mid- and late-1980s "
Here's that link...if you're interested, I'd bookmark it like I have and check in once in a while for updates (or to read the whole Dec 2, 2009 one)

BTW, one of the comments at today's Hubble observations of Pluto news conference was that those results have been used in planning the 2015 encounter...there might be some comment on that in the next PI's Perspective.
