In addition to several new models yet to hit the streets or even be officially unveiled, you can add the Sony Xperia ST27 "Lotus". The mid-range phone was spotted in Japan by Blog of Mobile along with a few tepid specifications. This is in addition to the Xperia P, the new GX and SX, the Sola and the Tapioca. Slow down, guys, we're still trying to get through your obtuse method of name selection.
Core specs include a NovaThor 1Ghz dual-core processor, a 480x854 screen of unknown size, and (sigh) Android 2.3 Gingergread. The source says that it's possible that the phone will be released with ICS if the software is ready. They also report that the phone will come in two flavors, the ST27i and ST27a. The former is an international phone meant to be used on 3G networks all over the world, whereas the latter will use the 850/1900 GSM bands for American 3G, specifically AT&T's network.
Pricing, size, battery, and most of the other information isn't available, since the initial leak came from a user agent. Given the model number, it may or may not be the successor to the Sony Ericsson Xperia Active (above). We'll be keeping an eye our for any further leaks as the device nears release - whenever that might be.
