Tonight as I was driving by Huntington Scion I decided to stop to look at what they had on the lot. There was a new 06 xA. It has the tC mirrors and the front grill is different. The bottom molding on the front bumper where the older xA's fogs were, has a new cutout which resembles the cutouts from the tC. If this is the case then perhaps some new fogs may be on the way. Of course this is speculation but it would make sense.
There are other changes to the xA but those were the important ones relevant to us. There is a write up about it in the xA forums and the pics are there too.
Here are pics of the the xA:

Upon looking at the pics again, the cutouts are in the opposite direction of the tC. Somewhat like the IS 300. Keep your fingers crossed Scion/Toyota is planning on re-making the fogs. There is a lot of room between the side cutouts so they may just decide to use the old ones again in a style of the current tC and older xA's.
