NAD Near Future HT Products?

I've been a happy NAD user for decades starting with the old NAD 3020 integrated amp I purchased in college. I'm still using an NAD T753v3 to power my surround and for two-channel listening. Also running BlueSound Vault for all my music listening. Had planned on upgrading to the NAD T778 for more power (which I don't really need) and the touch screen capabilty. But I'm wondering if anyone has any insight into if/when they plan on introducing new models. It seems like the lineup hasn't changed in many years. I've been told the 778 would essentially be the same exact sound I have now. Would hate to upgrade and then hear the company is bring out a new line up soon.
