We're not talking about the B8 chassis range, which includes the higher line B8R though, we're talking about the B8RLE which is designed to be a chassis for a low floor city bus. It's related to the B8R, but it's not the same and to try and suggest that they are one and the same couldn't be further from the truth.
The B8R does have a number of coaches built on it in the UK and Ireland including the Plaxton Leopard and the SC3 as well as the non low-entry version of the SB3. But the BE order is not built on this chassis, it is built on it's bus cousin, the B8RLE, unless Bus Eireann made a mistake in their internal docs.

Well that would be my worry as well, especially when they only are going to have a 280bhp engine, which is the standard spec engine that is fitted to the B8RLE chassis.
It's just the chassis with something different being built around it, engines and other parts can be changed etc
All we can do is wait and see what actually arrives
