As much as I wish for it to be the Carrack, I'm willing to bet it's a new concept ship. Hands down.
That being said, I hope I hate it. Haha. Gaaaaaaaaa, my aching wallet!
Edit: please be the Carrack!
"Isn't". Haha. I was going that way, but I already felt douchy for the grammar correction, even though it was gone in complete jest! Haha.
Also, sorry.
Haha, true story. And I concur: whatever ship ends up fitting in that hangar (or whatever ship comes native to it) should at least have a jump drive, so as to be able to scout through jump points that are too small for the Carrack herself.
