Future teams
Cheever Racing ... the Aug. 28 IRL press release quotes Eddie's nephew Richard Antinucci as looking to get into the ICS (and get the team back into the ICS) long-term, if, of course, the $$ comes together.

Future races
The schedule will expand to 20+ races in 2009 most likely. Here are some candidates to be added to the docket.
Michigan International Speedway has mentioned they'd be interested in a return for 2009. We've had speculation on New Hampshire Motor Speedway returning to the IRL for 2009 if it loses a Cup date, coming from NHMS themselves. However, TG said in the unification press conference that the IRL had exhausted all potential ovals, and insinuated that it would likely not be looking to add any more.
Several reports out of Toronto have stated the city's street race at Exhibition Place is a potential go for 2009.
The Mexico City race has been mentioned as a possible addition for either 2008 or 2009
NHL co-owner Mike Lanigan promotes street/airport events in Houston and Cleveland. Lanigan is hoping to get one or both races on the 2009 schedule.
Barber Motorsports Park in Alabama hosted an IRL test in the fall and its owner expressed hope of hosting an IRL race someday. With unification, it's unlikely to happen.
Other North American CC races that are not in the proposed 2008 schedule, but were on the CC docket: Road America (a strong possibility for the future), Mont-Tremblant (a 50/50 shot for '09, perhaps), Portland (goner, almost didn't make it in '08), Laguna Seca (track rental, could make a merged schedule if Infineon ever drops off the list).

An NHL statement listed Graham Rahal and Justin Wilson's car numbers as 02 and 06. We'll see if those hold.
