"I see a lot of emphasis put on CFBE. Is it significant if this is achieved with mostly cost cutting and a minimal to modest revenue increase?"
Depends what you are interested in.
If you are thinking about dilution, then CFBE makes a big difference however it is achieved.
If you are thinking about whether demand is appearing, CFBE is not as relevant as how it was achieved (cost-cutting or revenue expansion).
If you are thinking about future product development, then savage cuts mean less investment and slower progress.
One thing we do know is that Solms' financial forecast incorporated CFBE by q4,14 in its assumptions. Now that this pillar of his assumptions appears to have crumbled, and in the absence of assurances to the contrary, it is safer and more prudent to assume Wave's cash flow isn't adequate and Wave will need to dilute. Of course, it's a probability thing. But when a key pillar fails, all of the architect's calculations become obsolete and the building often comes down.
Another interesting question: since it appears he didn't reach his stated goals, what happens to his performance bonus? - is it the usual Wave model? Heck. It's a guaranteed bonus. Or is it different?
