To be honest I didn't ask, I just kind of assumed it would happen. He did specifically say it would show up in the Outback, so perhaps it will go from there to the Legacy. I'm hoping for the same thing - I'd seriously consider trading in my '99 if they brought out a H-6 GT (with a 5 speed, of course).
'99 Legacy 2.5GT (WNTR-GT): removed intake silencer, K&N filter, 18mm SPD rear bar, 80/100W bulbs with heavy duty wiring, 205/55ZR-16 Yoko Nexus tires
'89 Mustang GT convertible (SUMR-GT): 9# intercooled ATI supercharger, TFS head and intake, Borlas, Konis, etc, etc...
