I didn't know that the tC was a US only car... I assumed that they were all Toyotas in Japan.
We love ours, it's a brilliant car, esp. for the price. I drove and priced a few in the same size/style range (focus, golf, etc.) and this is as good as it gets. Really thinking about getting an xB in a year or so also now, and I didn't like that car at all... until I sat in one.
I could see Toyota wanting to hook up TF versions of all 3 of these -- it's great PR for the line.
