As far as Hasbro is concerned - Alternators are dead so don't expect to see these over here.
Sorry for the yes - as I knew this was coming (referring to Arcee & Prime), but I've heard nothing positive from Hasbro regarding the ALT line, but please enlighten me if you will.
Actually, it was at the end of the article you posted...
"Alts not dead, just sleeping." Time for them to wake up!
