i've also heard/read somewhere that they will produce just above 2k a yr for north america. is-f owners will definitely stay special for quite some time. don't forget there is already over a yr on the waiting list in japan.
The number is roughly 300-400 a month for the USA and this is a number i've been saying since early 2007. That equates to just about 4,000-5,000 units a year. This is from my direct sources at Lexus USA.
