Update: GSMArena reports that an upcoming Samsung-branded Windows Phone 8, model number SGH-T899, has been leaked in a user agent profile on T-Mobile. This is most likely the phone codenamed "Odyssey" as its alleged specs support those previously reported: dual-core Snapdragon Qualcomm MSM8960 S4 processor, 4.65-inch 720p display, 8-megapixel camera, LTE and NFC connectivity. The article went on to add that the phone will come with 1GB of RAM.
During the Windows Phone Summit, Microsoft announced that all four hardware partners, HTC, Huawei, Nokia and Samsung, would be manufacturing new Windows Phone 8 devices. A little later on after the announcement, a WP8 phone lineup for HTC was leaked, with Huawei announcing on the same day that they would be launching a new WP8 device sometime in Q4 this year. These allegations were followed closely by rumors that Microsoft was looking into making their own WP8 phones.
Samsung has at long last joined the fray - unplanned as it is in its nature. Due to the ongoing Apple vs Samsung trial, Samsung has "accidentally" revealed at least two WP8 devices, nicknamed "Odyssey" and "Macro", in its court documents.
The Verge - "Both devices are marked as running on the Qualcomm MSM8960 chipset, a dual-core 1.5GHz system-on-chip that Microsoft has been using to test Windows Phone 8.
Described as an "iconic smartphone," Samsung's Odyssey device will feature a 4.65-inch Super AMOLED display with HD resolution and an 8-megapixel rear camera. Samsung also marks the Odyssey as an NFC device, suggesting it will support Microsoft's upcoming Wallet Hub and Tap + Send features in Windows Phone 8.
The Marco will include a 4-inch S-AMOLED display with WVGA resolution and a 5-megapixel rear camera. Both handsets will be LTE-capable and, if the documents are up-to-date, appear to be launching in Q4 2012 — matching the rumored Windows Phone 8 release date."
