Three more seats in the World Series by Renault appear to have been filled, with confirmation awaited on deals for Milos Pavlovic, Davide Valsecchi and Alvaro Barba.
Pavlovic has seemingly put aside his GP2 ambitions to return to the World Series for another year, inking a deal with Cram Competition, where he will partner promising young Briton Ben Hanley.
Although he tested with GP2 team Super Nova, the Serbian driver - who has Italian F3 and FNissan Light titles to his name - returned his attention to chasing the WSR crown after a winter test outing with Draco. Despite subsequently failing to land a ride with the former F3000 champions, he has landed a seat at Cram after toiling away at GD Motorsport in 2005.
Hanley was confirmed by Cram earlier in the week, having raced with the team towards the end of 2005. The pair replace Eric Salignon and Damien Pasini, who contested most of last season with the Italian squad.
Valsecchi also hinted at GP2 ambitions but with the F1 feeder series' 26 seats filling rapidly, appears set to join reigning World Series champions Epsilon Euskadi. The young Italian impressed talent spotters in both GP2 and WSR during winter testing, causing something of a scramble for his signature, before edging closer to Joan Villadelprat's squad.
Barba, who also caused a stir by topping testing times before Christmas while running with Pons Racing, is looking to step up after a difficult season in Spanish F3, and has apparently inked an agreement to join the Swiss Jenzer Motorsports team.
With the GP2 grid almost complete, a number of high profile hopefuls will also switch their attention the World Series, with Hayanari Shimoda and Alvaro Parente both being linked to the Victory Engineering team following the Italian outfit's recent tie-up with Carlin Motorsport.
Parente is already well-known to Carlin, having raced its Team Portugal entry in both British F3 and the A1 Grand Prix series, while Shimoda is looking to break back into a single-seater series after sporadic outings with Carlin's Japanese A1 entry. The sportscar ace has tested repeatedly with GP2 team Super Nova, but has missed out on a drive there for the second successive season following David Sears' signing of Jose Maria Lopez and Fairuz Fauzy.
