NTT DoCoMo has laid down the law in its press release touting the LTE service it'll be launching later this year, and it turns out that "Xi" -- in this case, anyway -- is pronounced "crossy." Of course, ultimately, they can call it whatever they like -- it's the service itself that matters, and to that end, we can expect downlink speeds up to a positively blistering 75Mbps, rolling out first in Tokyo, Osaka, and Nagoya in December followed by "other major cities and then additional areas of the nation." DoCoMo's accounting for handoffs, too, so you won't be dropped (theoretically) when you move between Xi and FOMA areas. 75Mbps seems a bit optimistic for a first-phase LTE launch, but hey, we're pulling for 'em. Pricing and hardware will be announced later; in the meantime, you can follow the break for the full press release.
