Personally, I don't have need for many more Glocks. I own a 17 and a 32. I can see myself purchasing a 31, 20, and 26, along with .40 cal barrels for the 31 and 32. After that, Glock probably won't see much more of my money except when I purchase the occasional spare part or magazine. Once I have a chance to test-fire a 37, I'll decide whether or not to add it to my wanted list.
Honestly, there aren't many other handgun companies that have a chance of seeing my money. Glock and S&W, the latter of which will probably be used pistols simply because I prefer the older ones. I'm developing a fondess for odd-ball or older 1911's, so Kimber and Springfield won't see me anytime soon either.
When I carry, I usually carry a Glock. It's simple, reliable, more accurate than I am, has perhaps the best "factory-standard" finish available, and unlike my S&W M27, I don't care very much if my Glock M17 gets dinged or worn. The trigger is comfortable and familiar to me, and its simplicity has reinforced safe handling practices. When loaded, it's just like a revolver - pull the trigger and it'll go bang.
My current collection consists of Glocks, N-Frame S&W revolvers (29-2, 27-2), and a Griffon. Oh, and a Kel-Tec P32 I'll probably sell soon. I plan to add a few other odd-ball 1911's to the mix, maybe a few more S&W revolvers... But really, it's time to start building the rifle and shotgun collection!
You know you have too many handguns when they won't all fit into a single range bag, so I plan to stop soon.
So, no, I don't believe that Glock is "losing its flower." As a happy Glock customer, they simply don't have anything further to offer me.
