If I understand it, they're already working on the next gen chips. Took them a while to get started on it so no delivery until at least February. At least someone's making decent mid-entry hardware that's not built-for-n00bs or $4000.
I feel that the Cube is a culmination of their research for a platform to house their next-gen chips and the current Cube offering with the BE100 chips is just a dry run. If the anticipated chips are anything like the Bitfury 55nm chips (or better), then that would be exciting. Just imagine a yield of at least 200+ GH/s in a very attractive tiny 5.3" x 6.0" x 5.8" package drawing similar wattage as the current Cube. I also feel that USB connectivity (with the existing port) will be implemented then for mainstream appeal.
I couldn't agree with you more. AM has allowed us regular small-time miners to be significant part of the network. Still, just like with any other company or business, profit is paramount.
