In this test with a mirror material from the online repository, reflections seem to stop somewhere around 20 bounces ans then go to a black blur... I made sure to set bounces to the maximum in the Pathtracing engine.

Any suggestions on how to achieve infinite mirror reflections? This is important for interior design.

Maybe the lens aperture is set to high, so that the bounces are blurred?

If you are using pathtracing then you have hit the maxdepth.

@face: Aperture is small... That's why the palm trees in the reflections are in focus.

@steveps3: Do you know if this is a limitation of the beta?

In reality how many times are "infinite" reflections really needed in interior design?

A slight camera move in your example will make them finite and renderer manageable.

You can't at the moment (and very likely for quite a while). For performance reason we allow only a limited amount of bounces and even if you set the limit very high, the russian roulette mechanism will terminate paths before you reach that limit. You can force it to trace the rays for hundreds of bounces, but this will only increase noise and massively reduce performance. -> Not recommended at all. If you want to render artificial situations, a different renderer is probably a better choice.
