I think GG needs to consider that maybe the DCC line has run it's course, meaning that maybe it's just not that type of modules that the modern gamer wants anymore. I am pretty sure there is a 4e market for good adventures, but if GG's DCC's do not sell enough, then perhaps it's the style that needs to change. Of course, this is all assuming that the 4e DCC line doesn't sell well anymore.
Yes, I'd certainly interpret sagging sales of 4e DCCs as an indication that the most successful adventure module line of all time had run its course and needed fundamental change.
But definitely, definitely not indicative of anything to do with 4e.
