Just saw the IB A319 with 2-2 seating pics. Does look nice.
But I think TP is still looking at the long euro routes opportunistically. And I think they need to prioritize long-haul C to flat seats.

OS has been rolling out the Recaro seats which is even worse comfort wise than TP, IMO.

And yes I would really like to see proper C in Europe but I don't think it will happen. The Euro-Biz class is here to stay for most companies as it provides the flexibility Airlines need (1 flight half cabin C, the next 2 rows only) and they are having a hard time monetizing Euro-Biz as most companies only pay for Y in Europe.
But I think there is still room to improve the experience in current Euro-Biz.
