Externally, it should be very, very close.
Mine was the shroud kit, built for a TM thommy, Snow wolf always was a PR, from the original build.
The main differences , i think, will be…
1: Mags. Snow wolf airsoft had a thumb wound , wheel at the bottom of the mag, spring fed mag. These PR’s have been converted to be a spring compression, spring fed mag.
The gelsoft thommy/PR has an all electric mag, with terminal on the mag.
2: countdown meter
I hope these are better than mine. Mine had the ‘counting light gate’, which jumped and jumbled shots. I ordered a ‘straight countdown when trigger is pulled’ circuit , but didn’t want it pulled apart again for no good reason.
I hope these have been fitted with a ‘straight countdown’ meter, it appeared to be working much better in the xforce vid.
I only handled my SW airsoft in NZ for a short time, i think there will be very little difference between them externally, and buildwise. We’ll find out soon enough! 
To be honest, i was much more excited getting my first one, i finally was able to have a firing one in OZ.
I’ve had mine for awhile now, and whilst i’m looking forward to trying these new ones out, i was definitely more excited the first time around…
Nevertheless, there will be loads of people, over the moon to get one, for the first time.
I would now reserve that level of excitement, for a Gen 2 Burton…!!
I’ll try to post a pic of ALL my (Aust) pulse rifles in the one pic…might need a wide angle lens…!!! 
Can you believe there was a time, i had none…
I think a big part of collecting, is the thrill of the chase / hunt…
