I thought i couldn't find any more new reviews but found a couple.
HTC Makes the One the Android to Beat - Katherine Boehret - The Digital Solution - AllThingsD
Piss poor review imo.
From Know Your Mobile:
HTC One review: Prices, Specifications, Reviews | Know Your Mobile
5/5 review with well balanced pro's and con's. Good read.
Finally, a brilliant video review from MobileTechReview:
HTC One Review - YouTube
Only 27mins long but very comprehensive and engaging.
