So next year when Sydney Metro to Sydenham operations begin, T4 services will stop at platforms 3 and 4 at both Erskineville and St Peters. What will happen to services that currently stop at Platforms 1 and 2?

It all depends on when Bankstown line shuts down, until then you would expect T3 services to operate as is. Not sure if they will still enforce those stops on T4 services (you would hope not) until such time as that occurs.
Can't imagine any changes to T4 services until anything is changed with T3 services (the original plan was for the metro line to have been completed to Bankstown, thus removing T3 services from that part of the network which would have then allowed for T4 services, but that's not the case at this point).
I seem to recall one of the options (or was it The Plan?) for T4 trains was to "transpose" the express and local services such that express uses the Illawarra Local lines (basically trains departing platforms 1 & 2 from Hurstville - the ones that don't have a platform at Wolli Creek) and local/all stops use the Illawarra [Main] (platforms 3 & 4 from Hurstville) - for which I suspect this would need the paths freed up by the removal of T3 trains at Sydenham.
As for Erskineville and St Peters, I think that same plan would have seen the return of some Illawarra line services stopping at Erskineville and St Peters, in a similar vein to how they more or less took over the East Hills line services out of Tempe.
Guessing a handful of T8 peak trains would still travel via Sydenham as they do now, so those paths still need to be kept free if so.
I agree that T3 services will continue to operate as they do currently until the Bankstown Line is shut down for final metro conversion and commissioning. Bus replacements will operate on the Bankstown Line to and from Sydenham until the metro begins operation on that sector.
The peak hour T8 services via Sydenham will also most likely continue until the signalling and power upgrades on the Airport Line are completed to allow all peak hour T8 services to run via the Airport Line to the City Circle. I believe that the T8 services via Sydenham in the peak currently alternate stopping at St Peters and Erskineville, shared with the all stations T3 services on the Local through platforms 3 and 4. Not sure what the status is of the Airport Line upgrade.
As for T4 services, it again depends on the removal of T3 and T8 services from the Local and completion of the Airport Line upgrade. "The Plan" for T4 and SCO Intercity services is to swap the current express and local all stations services between the Illawarra Main and Local tracks at Hurstville as you mentioned. The Hurstville all stations services to Bondi Junction will operate from platforms 3 and 4 (the Main) and the Cronulla/Waterfall and SCO services will operate from platforms 1 and 2 (the Local). The Cronulla/Waterfall express services will cross from the Local to the Main south of Wolli Creek Station, merging with the Hurstville services, in a most likely all stations pattern to Bondi Junction. This could potentially provide a frequency of 24tph in the peak for all stations from Wolli Creek to Bondi Junction with the proposed digital signalling upgrades.
SCO Intercity services will no longer run to Bondi Junction and instead will continue on the Local to the new Erskineville crossovers, where they will cross to the Illawarra Dive and Sydney Terminal. There will also no longer be any suburban services running on the Local via Sydenham (platforms 3 and 4).
The Local will be underutilised with only SCO, and potentially SHL Intercity, and South Regional services using it to Sydney Terminal via the Illawarra Dive. If the Airport Line can't be upgraded further to 24tph with the digital signalling upgrade, then there would still be the option to run more T8 services via Sydenham to the City Circle. If the Airport Line can be upgraded further to 24tph for all T8 services, then the Illawarra Local and Main from Erskineville Junction to Central will virtually become redundant, although they would most likely be retained for trackwork and emergency diversions.
