Status of Xbox360 HD DVD addon People continue to remove the sentence However console add ons of this type are traditionally and notoriously relatively unsuccessful due to poor sales saying that the addon is selling well I contend that when put into perspective it is not selling well not selling poorly just not well With 10 5 million Xbox360 s sold 1 and more than 100 000 addons sold the attach rate is quite small for something that is supposedly selling well The maths I ll use 150 000 to be generous 150 000 10 500 000 100 1 4 With pre release claims from Microsoft that they would achive a 30 attach rate the current figures are less than good Hense I will be reverting the deletion of the sentence
