Disappointing for Ivan that he can't compete in his favourite race this year. Though it could have been a blessing in disguise.
If he would focus on the Vuelta.
I don't understand why Basso's immediate reaction to being forced out of the Giro is to declare his ambition to race the TDF? Here is why he should put all his energies into the Vuelta in 2013.
1) Competition: Froome, Contador, Rodriguez. These are the three top riders who are focusing their energies on the TDF. Anton, F. Schleck, Nibali (the main top Giro rider I see focusing on the Vuelta). The three who are possible top candidates in Spain. Hardly comparable. Basso cannot expect to be competitive against the competition in France.
2) Parcours: It's not a time trial heavy Tour this year (65 km ITT), but still better suited to an all rounder than the Vuelta, which has eleven uphill finishers, making the 40 or so kms of ITT virtually irrelevent. Ivan has always been more pure climber than all rounder. In Spain, many stages have just the one climb, but the stage in the French Pyrenees of over 230 kms is perfectly suited to his diesel engine, and the kinda stage where in form, he could win the race overall, or at least claim a place on the podium.
3) Time/Date: I felt that Basso could have done a little better in the TDF of 2011 with a better preparation. Then he finished 7th. Already he is behind the eight ball this year with this cyst issue, only two months out from the start. Coming six or so weeks later, Basso has more time to get himself into shape for the Tour of Spain. Perhaps he should ride the TDF, but for me if he did, it ought to be strictly as training.
