I think the price war already started in two fronts.
1) Low price plans -- below S$25 for no frills plan -- SIMBA 2.5Gbps plan at S$20 and Whizcomms "aggregated" 2.5Gbps plan at S$21.60.
2) High price plans expecially 10Gbps plan with routers -- suddenly all below S$70 now. If you take out the free router cost, the monthly cost is actually cheaper than the current 2Gbps plan pricing.
a) Singtel 10Gbps Enhanced Plan with free TP-Link HB810 BE22000 WiFi 7 Router at $69.72/mth for new users (recontract users at S$84.72)

Starhub also has an bundle with superb value if you need those contents: HomeHub+ UltraSpeed at S$87.96
c) MR HyperSpeed plan with free TP-Link Archer AXE300 at S$59.99 per month. The gamer plan is at S$64.99 per month with the same free TP-Link Archer AXE300. [Edit: need to top up S$150 for the AXE300 router].

3) In year 2024, I believe 1Gbps plans will drop price and become the base plan (S$20 to S$30) like the current 500Mbps plans.
2.5Gbps plan will be the main stream like the current 1Gbps plan (S$20 to S$40).
Dual 1Gbps plan will probably become a niche or totally gone.
10Gbps plan will remain at the high end for many years but the pricing may further go down to S$40 to S$50 (say no free wireless router, or with basic wireless router).
