More than 2 nodes

Do you plan (and when) to offer more than to 2 node HA? For example 4-5 nodes which will offer more speed and availability?

Yes, multi-node config (sync and async) is coming. Soon. Very soon

It does not work as you expect BTW. With more then three nodes doing synchronization with each other to keep distributed caches coherent the whole thing saturates network and brings extra latency killing performance. So it's pretty unexpected to see more then 3-4 nodes in homogeneous config.
What's going to work is using multiple redundant nodes keeping shared cache as a gateway to second layer of nodes acting as a storage rather then processor/cache nodes. Take a look at Fujitsu grid storage systems. They are built with referenced architecture in mind.

Hi,

that is what I'm asking for. Our farm is not as fast as it should be with one node down, so another backup or MPIO node will be very needed. Do you have ETA? How it will work?

Thank you

We'll provide configuration with no performance degradation on partially broken cluster. ETA is this Fall. You may get early experimental builds sooner.
