The most interesting part of this article is that this HTC One will retain it's quad core processor which, as stated will need the WP8.1 update. So if we get a release date for this then we will have some idea of when WP8.1 will be coming. Along with WP8.1 there will be a whole new batch of devices as the rumours suggest that many of the manufacturers have been holding back multi devices for WP until they could support similar device specs as found on the Android platform. With WP8.1, I think the WP platform really does become a serious player.
P.S. I too am eagerly awaiting the launch of the Nokia Lumia 1020. However, with it's launch coming on the 11th of July I am worried that it will be launched pre WP8.1, something that will massively damage it's overall and future appeal.
