For the transport in particular, I never remember seeing one of those things shoot in any incarnation. It seems a bit like a move to get people to play more missions. You put in a token like the senator's shuttle and no one uses it, at least I've not run into any missions yet, but if you make a big model that gets people invested and diversifies the gameplay more. I'm increasingly liking the idea of storm trooper transports and a capture the corvette mission.
In the EU cannon it is established that they are in fact armed, just not well enough to take on capitol ships which is why they need an escort.
Personally I'm into it. Being someone who has come from 40k I enjoy the dynamic of having a "regular size" and a "super big special rules for awesome models size". I will pick both of these up when I have the cash and use them in fun games and mega battle style stuff.
I hope that they don't become part of the tournament scene though and that dog fighting stays the norm. I think we can hope that that will stay mostly true because of the uninterrupted wave release schedule.
Ah cool. Where was that? I'm mostly going off of X-wing Alliance here. Something like a blaster turret and 1-speed movements would make some sense.
Umm its just mentioned in different Rebellion Era EU canon. I mean it was mentioned off hand in Choices of One (just finished reading recently). I don't know particulars of what kind of load out it would have but I would imagine something in the order of the cannon upgrade cards, Ion Cannon, Heavy Laser Cannon, things like that. Not many, but enough to stave off a few small fighters at a time.
FWIW, Wookieepedia claims a variant GR-75 is equipped with "Twin fire-linked laser cannon turrets" and of the 7 crew, one of them is a gunner.
Looked to me like there were 2 or 3 in on the attack on the second death star.
That's true, I think they were there as kamikaze ships, though.
