I wish FFG would just say whether or not they are going to do an SSD....
I honestly doubt they know.
I'd imagine that they're still working out on the easy ships to fit in. Like say an Interdictor, or other ships that are between the 150m and 1600m sizes.
Once they have a number of those in then they'd consider if a SSD is possible or not, and how to make it work. Until they get to that point I don't expect they'd bother saying anything either way.
