I -might- consider getting the Tactical version of the Vesta, but I ain't gonna be spending a dime of real money on it.
In fact, what's the point in adding new ships anyways? It's not like the current line-up isn't suitable for the current endgame content. The biggest difference, is a new skin (appearance) and possibly new officer layout. But overall, it doesn't change your performance in completing any of the content.
