As you've noticed, the trend of Infinity products is to remove blisters and consolidate the figures into boxed sets. However, there still is 3-4 blisters being released every month. Five new Infinity products pop up every month.
You may think this is a good thing; after all, variety is great. However, imagine the nightmare that Corvus Belli has keeping every individual item in stock. Imagine the nuisance that each local store undergoes trying to keep Infinity in stock.
Regardless, I was looking at my local game store's stock recently, and being the online retailer they are, they have everything listed with a number of products next to the title:

Note these values for popular games:
1838 Reaper Miniatures Items
552 Warmachine Items
420 Infinity Items
349 Malifaux Items
343 Hordes Items
221 Warhammer 40,000 Items
212 Warhammer Fantasy Items
Reaper is clearly up there, but their main focus is having an absurd variety of everything. Want a Fire Elemental? They've got it. Oh, you want one with legs? Got that too. Want one with breasts? Yep, that too. Overall, though, they have multiple lines and no game to call their own.
Both Warhammers have the least number of individual products, but that's because they focus heavily on boxed sets.
Malifaux is the newcomer to all this, but they're already making the move to each master being in boxed sets. Their product number doesn't explode as much as it used to.
Warmachine and Hordes are up there, but
PP has recently been focusing more towards boxed sets as a whole and making more of their cookie-cutter Warjacks that have drastically different stats for minor aesthetic changes. Regardless, they release maybe 2-3 products a month (if even) and that's between their two lines.
That leaves Infinity. They're on the higher-end of a single game with the variety of products. They still add 4-5 new items per month
every month. Great for fans, but it's a problem for LGSs that want to carry the game.
This is a problem, and I expect Corvus Belli will be addressing this in the future. Expect a lot to change.
Or, then again, they could just go the route that Reaper does and make a kabadrillion models.
