The first segment is already covered by Quadro and its ilk, and nobody is going to stick Tegra chips in a server because they waste budget, resources, heat, and space on ARM cores that are much less efficient for the workloads they target than big beefy gpu cards. If they are doing CUDA compute in a server environment, it is on dedicated CUDA hardware, not some APU. Understandably, though, they pretty much dominate this segment with their current crop of "business" class gpus. FireGL isn't even close to the market penetration Nvidia has, and CUDA is hyper-optimized by them on purpose whereas openCL targets the second segment.
The second class is composed of developers who won't use a non-open GPGPU standard to write apps for in an environment even more hostile to Nvidia than the desktop where their only competitors are Intel and AMD. In mobile they don't have close to the market segment they do on desktop and nobody will platform lock themselves to Nvidia hardware, especially when every other player in the room ships openCL.
I think this announcement might be even worse for Nvidia than the mediocre performance figures on Tegra 3 and the lack of enthusiasm from manufacturers to adopt Tegra 4. It is obvious ARM in the next ~5 years will become the new mainstream compute platform for the consumer market, and GPGPU on these devices as they become more powerful is an obvious optimization path for hardware that needs to be exceedingly power efficient. Not using the industry standard and trying to stuff their (albeit, solid and well supported) 6 year old GPGPU implementation is sealing their fate if the rest of the mobile world starts adopting OpenCL in retaliation.
Going down a path to their own proprietary way to do things (as per their usual, to be honest) is going to alienate Nvidia from hardware segments they think this kind of move will get them a monopoly in.
