Apparently both handsets will be named as part of the Omnia line of Windows Phone handsets, of which we already have the Omnia 7, Omnia M and Omnia W. We'd wager to bet that the flagship codenamed "Odyssey" will end up being called Omnia 8, to indicate it is Samsung's best WP8 effort, while the GT-I8370 "Marco" can be anything else.
The specs are whispered to be the SGSIII 4.8" HD Super AMOLED display (previous rumor stated 4.65") with 8MP camera on the back for the "Odyssey" flagship, and a WVGA 4-incher with 5MP camera on the back for the "Marco" mid-ranger. Both are powered by a 1.5GHz dual-core Snapdragon S4, meaning there might be LTE thrown in for some regions, and offer an expandable storage via a microSD slot, adding to the 8GB of internal memory for "Marco", and 16/32GB for "Odyssey", which could be heading to T-Mobile.
Those of you who are hoping that Windows Phone 8 handsets will be cheaper than, say Samsung's Android phones, are in for a bit of disappointment, as the component goodies lock in a price range of $430-500 for the "Marco" in Europe, and the cool $610-740 for the high-end. After all, we might have the same components in "Odyssey" as in the US Galaxy S III, and the price to match, leaving the design as the big unknown. How will Samsung's WP8 offerings fare against those of Nokia with their free lifetime navigation bundle, and preferential Microsoft treatment, remains to be seen.
