where more cpi/dpi ? all I see is 12k, and where did you compared IPS ?

Ah, this is how they advertise them, 12k vs 7.2k dpi/cpi, and 350 ips vs 240 ips (more in Truemove3, less dpi in Truemove1), and tracking performance is something above 3310 sensor and as great as 3366/3360 (or as you could say - hard to see the difference between them two Tm3 <-> 3366). It's agreed Truemove3 is top sensor in market now, and logitech is trying to do something about it, haha.

... They were top for 3 years, now SS time! Truemove3 (350ips max speed - overkill..) and budget Truemove1 (240 ips max speed, about right!) is basically about sensor jitter levels reduction at lower DPIs (400-800 something), what logitech didn't manage to do(!), but still logitech's best mice with top optical sensor 3366 are great, close to perfection, the tracking in quake for me is flawless with it

This new sensor naming should confuse us even more now, this marketing though... lol

Microsoft released a Pro version of this mouse. It’s called Microsoft Pro Intellimouse and it’s based on this MS Classic Intellimouse. The main difference is in the used optical sensor - Pixart PMW3389. It’s 16k dpi flawless sensor used for example in Razer DeathAdder Elite. MS also used better micro switches and added rubber grips to side buttons. This mouse is manufactured in two colour variants- grey and white. Light on the tail of the mouse body is customisable.

Good spotting, I got it for -25%~ cheaper 8months ago, but I don't feel like using it, setting it on 1000mhz, it's a nice product tho, and sensor is PAW3389, not PMW, though has excellent tracking like other top sensors and shell materials nice, cable flexible, but i usually want to go back to logitech's mouse (100grams~) after 10 mins of using Intelli Pro dunno why, it's surely not the shape, dunno, just the overall feel in game not as tight/at home as with mx518/g402/g403/603/g502
