Fuji X20.. where is that 50 list ?

I was able to locate 2 sources that mentioned the "50 improvements" claim- techradar and mirrorless central- both are UK websites and both were very brief "preview" type  reports, each with a brief rundown of new features.I did not find any other source making similar statements and in particular, none from Fujifilm directly that  makes such a claim. FWIW, I would  assume that the original source would likely have  been a distributors representative  of  Fujifilm UK and  not officially from the parent company.
