I was wondering that myself, there are a number of issues going on here, TTXGP and the FIM e-Power series are going along quite well whereas I was particularly disappointed with the TTZero race this year, especially with regard to TT Spectator reactions 'prior to' the race.

I just wish the various factions involved in ZEV racing would finalise both a standard and race series to allow both circuit and pure road racing to progress quickly with the best ZEV motorcycles competing.

I covered the 2010 TTZero event here:
