I'm speaking theoretically here, I'd be surprised if they went back and made old companions SGR compatible any time soon.
If they do retroactively add non-Chiss jokes for Chiss in the Smuggler line, then I'd really consider that Bioware would actually give thought to having retroactive companion SGRA's. However, I am going to assume they'll only have the two obligatory "I think you're pretty/handsome" options on Makeb that lead to sod all and call that "equality".
I wrote "SGRs". This echoes Jeff Hickman's words from his blog here.
"Secondly, I want to reveal today that we are adding SGR with some NPCs on Makeb and do intend on pursuing more SGR options in the future. More details to come!"
Let's get this thread back on topic please.
I missed the word "companion", though I'm surprised you consider two [Flirt]s to be full blown romances.
Fine. I want Vector.
