there was never much of a terminal at LCK Rd End anyway. It's just a bus stop, a cul-de-sac, a portable toilet and a office(i think?) that isn't TIBS/SMRT's.
Makes sense to centralise all of their terminal offices actually. The staff at all those offices can work with much better resources at the respective interchanges than instead of the tiny container offices

They also have proper snack shops and canteens too (although Sembawang Rd End terminal has one, kinda rustic. Jln Kayu used to have one, but it's been boarded up)
For Sims Place and Ghim Moh terminals, my thoughts are that even though they may be closed down, 100 111 64 will be rerouted in such a way that they'll still serve those estates. Both of these estates are kinda medium sized (and have great food

) and the only other services serving them 92 and 125 don't exactly have good frequency.
Queen Street will never be closed down, that's what i think). It's a convienent transport "hub" to get to JB, with all those M'sia taxis and the SJE and Causeway Link stopping there. Tops they'll maybe merge it with the Lavender St coach station?
