Does that really matter...
Ask the current SD7 owners that same question. It certainly does for everyone who owns an Audya!!! We are not looking for a downgrade, but a serious upgrade.
If EVERYTHING in my current Audya can be copied over & used as is, I'll consider it as an upgrade despite the outward differences. Else, I'll patiently wait for the actual newer version of the Audya which should show up rather soon after this.
