I would think the next versions of the 50/900 will have Pratts on them.
There will be no next version of the Falcon 50, the Falcon 50 is now out of production. The last two are currently in the final stages of completion, I believe.
In over 17,000 + hours of flying jet powered aircraft I never had a jet engine fail. I have had to shut down 3 engines to prevent further damage.
1. CJ-610, Jet Commander, loss of oil pressure on rotation. Oil line ruptured.
2. JT8D, Boeing 727, CSD failure, CSD failed to disconnect, shut engine down due high oil temp, during climb out.
3. TFE-731, Sabre 65, loss of oil pressure on takeoff, aborted takeoff. Plantary tower shaft failed.
All three engines remained running until I shut them down.
As over a third of my flying time has been in 731 powered aircraft, Westwinds I & II, Sabre 65, Falcon 50/900 I must be pretty lucky.
(On the CJ-610 and the TFE-731 all the oil came out, you talk about a mess. Not as bad as when I blew an oil cooler on a DC-3, but that's another story.)
