Would echo the other comments in another respect. No need to panic or get depressed one would hope. If your PS2 or PS3 loco dies and cannot be repaired with available DCS compatible parts, you replace the innards with either an electronic E unit, or an ERR TMCC command receiver ± sound, or anything else that may become available in the future.
If you fancy DCC, that's another route to go.
One way or the other, you obviously lose some PS2/PS3 capabilities and need another system to control those locos if you don't already have a TMCC/Legacy/DCC system.
As noted, any failures or availability problems will occur quite gradually, giving you time to make such decisions and fund them. Does not require your making a decision now or even for a year or more, perhaps many years if DCS/PS3 parts and components remain available, as promised by Mike Wolf.
