I think the main favourites are: Contador, Basso, Menchov, Tondo, Uran, Mollema, Brajkovic and Scarponi. Rein Taaramae is also in a startlist but he wanted to skip Catalunya this year (in the end of
this article).
Dont know what to expect of Di Luca, Anton and D.Martin.
The last time Di Luca rode well on the long climbs he was banned

I don't know what is the current form of Igor Anton, whether on not he targets this? Anyway he won the Vuelta stage on the Vallnord last year

D.Martin was great in 2009 edition, but he said about Pais Vasco and the Ardennes week as the first this year's targets, though he said it before the Catalunya route was announced
