Per todays (13 March) annual Skoda financial presentation, seems the Fabia, Kamiq and Scala will stay in production until end of decade about 2029-2030. There might be a mild hybrid version coming at some stage

The earlier plans to replace them with small electric cars have been delayed until end of decade. European demand and EV build capacity are the reasons.

Seat-Cupra also had Financial presentation (1-2 hours later) and seems the Ibiza and Arona will continue for about another 5 years too for same reason.

Not sure if the similar VW models (Polo, Taigo and T-cross) are also going to continue for a while as petrol models, due to lack of electric alternatives yet.

At the end of the day car makers must respond to the market as they see it.
