After reading through the press release PDF and watching the conference from Softbank, I have come to the conclusion that the only phone fitting the description is the HTC Desire. The only details that Softbank has released so far is that the phone will be running Android with a 1ghz Snapdragon processor, have wifi and a 3.7oled display. It will also have access to Google services and the Android marketplace. The following is from the Softbank PDF:
I hope that this will be released early March as I am really wanting to get one. I phoned Softbank asking about a release date and they told me that there are no details available for this device. They indicated that they usually have the phone in the database two months prior to release indicating the phone may be released around June.
