When I ordered the Harmony this Saturday I discussed with my local shop couple of options. He mentioned to me the the Soundcenter for the 88" also a 77" can be fitted, but not a 65". So it looks like there will be a separate SKU for this heavy piece. He expects the Eclipse in August, with an updated way to mount the screen on the sound center, he also mentioned the screen will be sitting 5mm higher on the sound center. But no positive information if the "old" sound center can be upgraded by a a new mounting kit (potentially nice opportunity for STB Brackets)
I would love to see B&O care more about our heavy investments as a customer in the brand to support future upgrades path. B&O has been never good at that. I am almost sure that a lot customers would upgrade the electronics in a eclipse or harmony for future formats, or room correction systems or what ever.
Also think about the dealer if there is an upgrade kit for the Eclipse form the the old panel to the CX, a lot of extra business and a good way to get in touch with customers. At least my shop would love to see this.
