Discontinuation of Oriel won't really affect people who have already bought this, just like introduction of new Civic X shoudn't disturb the life of Civic 9th Gen owner. For someone thinking to buy Oriel right now, his main concerns are the price, long waiting time and low quality performance or build quality of the civic delivered to him. Even if Atlas tomorrow announce formally that Oriel is being discontinued in 2 months, it shouldn't really affect the existing and potential owners (who buy before the discontinuation).
Personally speaking, as long as Oriel is available, running better on normal petrol than Turbo, it is little sense for me to go for Turbo.
