I know it's not definite, but Andrew Clem's site works very well at illustrating my point. Just hover over the "Yankee Stadium II" link, and you will see that the front of the upper deck (I consider the terrace seats to be the upper deck, by the way) has moved back around the entire park:
Andrew Clem - Yankee Stadium. 80 feet might be an overstatement, but it is certainly farther back.
There may be less foul territory behind homeplate, but not down the lines. In fact, there may be more foul territory in the NYS down the lines than in RYS. Also, Pedroia is right in saying that NYS is quieter than the RYS. One reason is a lot less people. NYS is never at full capactiy, I ALWAYS see empty seats in the Legends, Field, and Main Levels. There are probably a lot of empty seats in the Grandstand, but since it's so far away, it's hard to even notice it on TV. Another reason it is so much quieter is because there is no overhang of decks, and thus no echo. Pedroia is used to Fenway, which gets much, much louder than NYS ever will, even if it has about 6,000 less seats.
