Added to that, Greg Beck was speaking very postively about the TEAM programme in the IRL and was hinting about a full time team. But we'll wait and see what happens there.
Eddie Cheever mentioned he wanted to run a road course only schedule for Antinucci
Jon Herb said at Texas that he planned to purchase more IRL equipment to run in 2008 but not heard much more from him
and SAMAX said they will be back in 2008 but there were strangely absent from Cavins list
Tom Anderson was making some mumbles about 2008 as well
Interesting that Cavin has Mutoh going to AGR though, perhaps that will save Matsuura's seat at Panther?
