WJAR is getting a new set (their first in about 15 years), and expects to be HD by the end of the year.
WPRI is remodeling their newsroom, and also expects to be HD by the end of the year. They've also been producing political debates in 16:9 this year, and their ticker, school closings, weather info ticker, and most of their IDs, promos, etc. are in HD.
WLNE is bankrupt and for sale. Enough said.
