Why am I not all that surprised?
According to Motorsport-Magazin (German), Michael Schumacher has canceled his eagerly anticipated return to the Formula 1, and will not race in Valencia on August 23rd.
Of course, the Schumi effect already helped organizers sell almost twice the number of tickets as had previously been sold. This cancellation is likely to fuel a lot of disillusion and anger with those people who were sold the chance to see a bit of racing history.
One thing is for sure — this is terrible news for Valencia, at a time when no more is needed.
