Sigma buys CopperGate - going head-to-head with Broadcom?

Sigma Designs is building quite a home networking portfolio. First, there was the acquisition of Zensys, and now today an announcement of their purchase of CopperGate, they look like they're going to go head-to-head even more with the likes of Broadcom in the advanced gateway, set-top box, and connected CE space, as Broadcom is a big proponent of MoCA.
