Is there future plan to scale traffic of wpmudev hosting

One of my clients site passes 1M traffic per month.
In the case that I tried to migrate that site to wpmudev hosting, it seems that even level 4 is not enough.
I am very attracted your hosting system, so I want
to know whether there will be any solution for that case, such as auto scall, more upgraded plan.

This is just question to decide to use wpmudev hosting future.
