We recently learned that Sony will be launching the Xperia Ion in LTE markets outside of the United States, and now there's a flurry of online rumors suggesting manufacturer may be preparing a second LTE handset for the second half of the year. Korean news site MT.co.kr reports via sources within Sony that an LTE smartphone "other than the Xperia Ion" could be making its way to South Korea as early as this June.
As XperiaBlog points out, this new, high-end device may match the Sony "Hayabusa", a rumored device which appeared on a leaked roadmap earlier in the year, alongside a ~€500 price tag. System info collected by benchmarking apps suggests the device may carry the model number LT29i, and use a Snapdragon S4 CPU with a buttonless 720p display.
Let's take this with an extra-large helping of salt for now, though, as we're still dealing with rumors and speculation here. However, it's no secret that the Xperia S isn't exactly packing the most up-to-date hardware, so we wouldn't be too shocked if a slightly higher-specced version was planned for later in the year.
