I was in the duel server with Tydeus, and tested the range of the new polearm thrust against the range of the two-handed thrust.
Tydeus was using a German Greatsword, with a range of 123.
I used a Shortened Spear, with a range of 120.
We assessed range by initiating a thrust attack against the other's down block. Tydeus thrusted against my down block until he was just on the threshold of still being in range. Without either of us moving, I then used the new polearm thrust against his down block. Even with a base -3 range, the Shortened Spear easily made contact with Tydeus' down block. In addition, I was able to move back just a tad bit farther away and still make contact with his down block.
From this preliminary test, it seems that the new polearm thrust animation is longer than the two-handed thrust animation by at least 3, but on a estimate probably closer to 8-10 reach.
