Well, meantime there have been some more news. The full line-ups of both ART and Barwa Addax have been confirmed. The signing of Sam Bird is a surprise to me, considering that he really hasn't shown much in so far. Considering that the difference of performance between ART team-mates has been significant in recent years, I suspect this is going to be the case next year as well... However, Perez has signed with Barwa as kinda expected and it's going to be a very important battle between him and vd Garde in 2010, whoever wants to have a bright future in motorsports. Younger and less experienced Perez has less to lose in this of course.
I think based on confirmations so far three drivers stand out, who could potentially regarded as 2010 title contenders: Bianchi, Perez, vd Garde. Wonder, which other driver could potentially be in the mix. D'Ambrosio has a shot at a Racing Engineering seat, but is struggling to gather the funds together. Valsecchi may race for iSport in the main series as well. If the Valsecchi deal doesn't materialize, Ericsson might get the second iSport seat - Arden is an other option for the Swede. By the way, one interesting news item for the long run - Ocean has signed Portugese Felix da Costa for 2011 (!) GP2 season. :p :
