yes. in comparison to outright purchase and installation of kit, this is *much* cheaper.  i'm just adding a point that it won't be able to run in a small footprint, which was the vibe that i received when it was released at "live!" this year.
the front-end management tools are light and run happily on modest resources -- but the actual orchestration on the backend requires more resources, especially as the instances are building and running.

i think the higher ceiling to hit will be in regards to (virtual) processors -- not the ram (as ram has scaled much faster than cores per box).  there are some pretty finicky requirements and while its possible to kind of "load share" around them -- if resource contention is felt -- the software doesn't exactly fail gracefully.

and i see this being a cisco-centric answer to an olive or even junosphere (though there are usage costs to junonsphere that i'm not well versed in).  i'm not exactly sure how this will be marketed or where it will be positioned.  i just know what my experience in using the software has been.  i see a lot of potential use cases with the software -- even though it has a *long* way to go in terms of features and software support.  i know that we're internally looking at ways that we can tie this in with different aspects of our labs and demos in an effort to help augment our physical demo's and proof-of-concepts.  it has a ways to go -- but it has promise and we're providing feedback to the dev teams on what we're seeing.

as you say -- for most customers -- it will come down to price vs. reward.  everyone has their own sweet spot.  it just all depends on if cisco hits that mark.
