Sennheiser's trade in deal seems to be way better than Shure's. The trade in value isn't linked to the model of the wireless being turned in, but based on the wireless being purchased.
That's the same way that Shure's is structured. They just do a god awful job of representing it that way with nouns and verbs in complete sentences.
Looking back at the the rebate page, it seems they are finally documenting which systems will be eligible for Firmware Fridays to make them comply with the new spectrum territory, and what that upgrade process will look like.
