They grow up so fast! The Space Marines have slowly been getting bigger over the past three decades. That's fine. An old metal Mk.7 is absolutely tiny compared to a new Guardsmen let alone a Primaris marine. Many (including me) have voiced the opinion that the Terminators were far too small. 

That has finally been addressed. The newest Tactical Dreadnought Armor suits are of goodly size and fine detail. Of course, now all my old, and really old Termies look a bit "Aren't you a little short for the Emperor's elite?" My first gen metal Termies got sent to be Space Hulk figures full time after the plastic ones came out. Now that I have 36 Deathwing Terminators? Hope that a newer and far more awesome Deathwing set never comes out? I'll just wait and see for a bit.

Shooty McRedemptor.  Really the same size, just legs straightened out and posed on a Tactical Rock. I'm certain this will be sold separately, just not sure it will get a new version with a few more options.

The older Carnifex does really bad posture. The Norn Queen is always telling it to stand up straight.
The new Screamer-Killer has listened to her. A little bulkier overall, the standing tall dramatic pose gives it the intimidation factor it deserves. Going to a 90mm base helps as well. I would love an Old One Eye re-done with this kind of extreme posing.

And finally we have the simplest, but very effective re-do. A little taller, more gangly, and more detail.
I hope the Hormagaunt and Genestealer get similar makeovers.
