There will be somebody with more concrete knowledge than I whom, I'm sure, will be able to offer a definitive answer.
With that caveat in mind, it's my understanding that Eastern disposed of the Embraers long ago. Furthermore, the Saab 2000s used to be leased in from GoldenAir of Sweden and on the Swedish register. Since then the Saabs have been moved onto the UK register but whether that means they're now crewed by Eastern guys or not (it was a wet-lease in the first place, I believe) I don't honestly know.
You may find that a new entrant at Eastern is given 'Hobson's choice' when it comes to type. If not, the Saabs and their glass cockpits would be quite appealing...
