There are already two threads with some info on this upcoming occultation of Pluto, so I thought to condense the info into one place for those who are interested.
The original predictions, from IOTA, the RIO group, and MIT are attached.

The latest prediction from the RIO group is also attached.
[EDIT] as of 12th June, another prediction from RIO and another prediction from MIT is available.
RIO:-

MIT:-

Both predictions are converging somewhat, in that the MIT prediction has moved a bit north, and the RIO prediction has moved south. Interesting times !
The casual reader will perhaps note that these predictions are fairly widely divergent. It is not possible to say at this time which one is the most correct; so any observer between Indonesia and Antarctica is in with a chance for the event, and should consider observing.
The last link above, from MIT, has a very good section on Observing Notes. Well worth reading. This section may help to answer the difficult question on filters, observing times, etc; although the prediction is for NZ and Tassie it is worth reading for anyone in the souther hemisphere.
Jay Pasachoff from Williams / MIT also writes on the planethunters blog, with some very nice info on previous occultation results and what people are looking for with the June 29 occ.
