Senna, coming to the end of his second year in GP2, has been racing cars for little over four years, having skipped karting and plunged almost straight into F3, and is thought the most likely to make the jump to F1, whether it be in 2009 or 2010. Of the rest of the field, only a handful are being touted as potential grand prix drivers.
di Grassi will be hoping that his strong return to GP2, after finishing as runner-up to Glock last season, will pay off with a possible Renault seat, although he may face opposition in future years from fourth-overall Romain Grosjean. Further down the final standings, Sebastien Buemi is due to test with Toro Rosso, alongside Takuma Sato, this week, while Karun Chandhok is expected to benefit from India's increasing presence in F1, and Kamui Kobayashi from Toyota backing.
Elsewhere, however, Luca Filippi could have blown his chances of graduating, despite links with Honda, after managing just six points with two of the series' top teams, and likewise Javi Villa, having been linked to a possible BMW role, after a lacklustre third season with Racing Engineering. Mike Conway, despite taking his first GP2 win this year, is openly exploring options in the US-based IndyCar Series, while several others have lined up rides in either A1GP or the new Superleague Formula series to keep them employed for the next few months.
