This is old news, also when I read the article I didn't see the base price that you put. I know that it's correct tho. Hopefully translates to a cheap price for US

Yeah, this might be old too, not sure http://www2.toyota.co.jp/jp/news/12/02/nt12_002.html

This has been discussed thoroughly, but you cannot convert the currency to obtain the US price.

The Prius base is 2,320,000 YEN ($30.5K USD) , but in the US it's $23,490.

My guess, based on the numbers:
RC $19.5 K USD, but not brought to America :(
G $24 K USD (FR-S)
GT $27 K USD, but probably not brought to America to prevent BRZ competition??

Or maybe FR-S will be between the G and RC, and BRZ is the G and GT equivalents.

Nobody knows, but we do know, based in this data, that the FR-S will definitely be below $25k.
