The booklet which comes with the "A-wing Wood Model" from Episode VIII gives a bit of info about both the original A-wing and the newer model which will be see in "The Last Jedi".
I noticed that the specs section from the booklet gives a lentgh of 7,6 meters for this new A-wing, which it is less than the 9,6 meters official length for the original A-wing, although visually both fighters seem very close in size (with the new RZ-2 seeming a bit longer than the older RZ-1).
I just wanted to let you know this info, because I am aware that the accuracy of the official length for the A-Wing (and the accuracy of the FFG A-wing model) has always been a topic of debate. Some people think that the 9,6 meters is a good measurement, and that the problem comes from ship models used in the movie being out of scale between them (or the pilot figurine for the A-Wing model being too big), and other people think there is no problem with the pilot figurine, and the official length for the RZ-1 A-Wing should be smaller (i.e. 6,9 meters).
The "Rebels" cartoon seemed to follow the 9,6 meters, as their A-wing seem bigger than those appearing in "Return of the Jedi" (the pilots look much smaller inside the cockpits), and there is a Bandai A-wing model which seems to be close to the 9,6 meters measurements. So I'm a bit curious about the possibility of the official A-wing length being oficially reassesed (as was done with the Millenium Falcon, which changed from the 26 meters given in the first Technical Sourcebook and RPG books to the current 33-34 meters, and the length for TIE Fighters, X-wings and Y-wings was slightly tweaked after "Rogue One").
