This is huge for not only Bruno but for Formula 1 in general. To see those two names together again is fantastic and I think it's the right decision. If they signed Rubens it may be a risk as he is nearing the end of his career and is not at his best anymore. But Bruno is up and coming and after some impressive performances for Renault last season he has a lot to show to the team. Of course everybody would love to see Rubens racing but the only other option at the moment is HRT. But we will have to wait and see what the future has in store.
Senna has made some brilliant performances throughout his career so far including a victory at Monaco in GP2 which was very special. Plus with age on his side , Williams have time to nurture his skills and develop them to make him a serious competitor.
Rubens has one option left for a full time seat and that would be to partner Pedro De La Rosa at HRT. With the team yet to confirm their second driver and Rubens posting on twitter that his future is "wide open" it may not be over for the fan favourite.
2012 was already shaping up to be a season to remember , but now it has become even more interesting and we haven't even hit pre-season testing yet!
