any new cards coming out to fill the gap between the GTX 960 and GTX 970?

I game at 1080p so I think the GTX 960 would suit me however to future proof my setup a bit maybe I should spend the extra money for a GTX 970. I was hoping Nvidia was going to be launch something to fill the performance gap between these cards at around the 250-275 dollar price range. Is there a chance of this happening any time soon? Usually the specs of new cards are leaked far before launch but I haven't been able to find much but rumors of a 960 TI or something similar.
