The guild summit speaker quite clearly says "We will not simply make the same companions available to both genders, that's not good writing"
That's incorrect. The actual quote is "We were not willing to go in and just change all the dialogue to work for the other gender. That is not writing. That is not good storytelling."
And if you think about it, it would make no sense for BioWare to declare a companion off-limits to SGRs if they're an OGR option. That would mean there were no SGRs available for female PCs, as every single female companion is an OGR option. Except SCORPIO, but she's a droid.
This does, of course, assume SGRs will be with current companions, not new ones. But I'm holding fast to that assumption until BioWare says otherwise.
