Any chance of them returning?

I assume the chance is low. Lack of spare parts and lack of drivers who would want to take them (apparently, that's a factor too). There's nobody here who can give you the proper answer because only the depot management knows such things, and even they can change their decisions based on the actual circumstances.

Approximately by the end of March all remaining 32Tr will be delivered. It will take some time for them to be prepared for traffic with passengers, but from that time, T203 will certainly not return to the streets. Before that, unless, as Mettal said, some driver would want to sacrify himself to work on these, they won't be returning as well.
