We've definitely heard this one before, but the buzz around a proposed $12B WiMAX partnership between Sprint, Clearwire, Comcast, Time Warner Cable, Intel, and Google is deafening right now, all based on a report in the Wall Street Journal. The plan is for Sprint to merge its XOHM wireless broadband division with Clearwire, and then take a total of $3.2B in investments from a host of other players: $1.05B from Comcast, $1B from Intel, $550M from Time Warner Cable, $500M from Google, and $100M from Bright House. The resulting company will be worth some $12B, and the WSJ says investors have given their final approval for the deal -- a rumor we've already heard with no meaningful result, so take it with a grain of salt. Or a whole salt lick, actually. We're not certain why Big Cable is so eager to dump money on Sprint after two previous ventures both folded recently, but if this goes down, it's a pretty big boost for WiMAX, which was looking pretty sickly lately. Still, asking consumers to have faith in Sprint and Comcast and Time Warner Cable is pretty ballsy -- between the three of them, they've probably burned everyone in America. We'll see where this goes -- we should have something official pretty soon, according to the Journal.
