Is there a method to the naming convention with these variants?

We have GT3, GT3R, GT3RS, GT3RSR; alternating back and forth between street and track only.  It made a little more sense before when the GT3R was a Cup/CupS.

a little.

Great announcements here though.  Don't they seem to be opening the curtain a little sooner this go-around?

 edit: can't wait to see the GT3RSRSR - that should be a monster!
