I noticed this new AEG brushless 1/2" impact. I would assume this means a Ridgid version is in the works.

480Nm of torque (354 ft lbs) is what is listed on their site.
One thing to note, the existing ridgid x4 is rated at 300 ft lbs (406 Nm) and 3200 BPM while the aeg version is rated at 360 Nm (265 ft lbs) and 3600 BPM
