As for ex-EG roster, it's surely a great investment for the org that will take care of them and they could play around with another coach if they think Bulba isn't that good for them. So, it's going to be 5 ex-EG + a new coach.
There is a rumour that Arteezy is going to be playing in Either Team Liquid or Team Secret next season so there is only small chances for all 5 of them to stick together. Things are not working for them though so there is really no reason for them to stick around each other any longer and also all of them cost alot of money to sign so I doubt a decent organization from NA region would be able to pick them up
There's an update from the Team Secret's official page that Crystallis is going to stay with them so that rumor is already broken if it's about RTZ going to Team Secret.
I think it's more plausible that he might be picked to go with Team Liquid but if the team itself (Ex-EG) decides to stay together and compete again to the next DPC season then that leaves nothing to Team Liquid.
While PSG.LGD has already parted ways with faith_bian who even said that he'll retire after the TI and xinQ is also out of the team.
