Despite the lack of ui numbers I ran a little test to see how much Ultimate each light/heavy attack generated. I used Soul Strike which cost 100 Ultimate and it took me only 2 light attacks to fill my bar, that means at least 50 Ultimate per attack. I shouldn't complain since I'm on console now, but I guess they decided this was the way to reach some parity with the PC crowd when it comes to dps and survivability.
