Futuremark has now decided not to offer a specific time frame for the launch of their newest version of their 3DMark benchmarking software, saying that it "will be ready when it's ready". From Neowin:

The newest version of the 3DMark benchmarking software for PC. made especially for Windows 8, was originally set for release by the end of 2012, and then for sometime in January. Now it appears that the software from developer Futuremark won't make January either and the company has decided not to give out a specific launch date this time.

What's the holdup? In a press release today, Futuremark seems to put the blame on its many partners in its Benchmark Developers Program. Company such as Microsoft, AMD, Intel, NVIDIA and others are part of the program.

 3DMark for Windows 8 delayed again, no timeline for release
