I was told that it will be getting hard to find sc2290's and the 2879's. They are being replaced with Mosfet finals. Is this true ???

Bin is correct, you can still get original 2879`s but the price has skyrocketed
They just had to stop making the original 2879`s because they now have to be RoHS compliant.
The New 2879A uses an Aluminum Nitrite insulator (color gray) on the header vs. Berillium Oxide (color white).
The Berillium Dust can be dangerous to humans, and you are not even supposed to throw them in the trash, they should be disposed of as Hazardous waste.
Same thing goes for the 2290.
The Very latest 2290`s called a 2290B with lot numbers higher than 8I and Above require 20 to 25% higher drive.

So you guys are saying there are Transistor Speculators?
