Wellp, I have finally felt my collection has ballooned by filling out enough where I can get away with making an entire shelf dedicated to TFs and working my Megatron collection into their respective collections within. That said, here's what I got going on for the moment:
http://jurassic-pedia.com/imgs/tfs/coll/tf-01.jpgI have one shelf dedicated to Megatron in the aspect of keeping variations and where certain figures won't fit in with other shelves. I'll eventually hope to incorporate other continuity Megatron's on this shelf that won't fit in with my other bits of my collection here and there. So an example would be Unicron Trilogy or things like that.
http://jurassic-pedia.com/imgs/tfs/coll/tf-02.jpgBelow the top shelf I placed my Bayformers here. I took out the "Gathering at the Nemesis" Blue Soundwave and The Fallen for the moment as I really don't want to display them at the moment. That said, they're in storage. I am probably going to have to play with this one again when it comes time for TLK Megatron Voyager and Leader as the shelf is pretty full. I might have to move the chess set behind all of them to make room for more Bayformers basically.
http://jurassic-pedia.com/imgs/tfs/coll//tf-03.jpgMy Generations Decepticon shelves that will also house variations of characters and might hold a few CHUG Megatron's as well, but for the moment the only Megatron that will be here is the CW Leader Megatron.
http://jurassic-pedia.com/imgs/tfs/coll/tf-04.jpgI gotta say this is my first time displaying all my Beast Wars (and related) together on one shelf. The first time I've had Maximals and Predacons side-by-side. I'm super stoked with how it turned out actually.

It will probably be expanded to incorporate more Autobots here in the future, but the Unicron portions won't be growing much aside from troop building. Unicron is much too big to put anywhere else but this shelf. As for my Autobot side I do hope to actually get Cybertron Primus at some point and put him almost in a wrestling match with Unicron in the end.
Overall I'm pretty happy with having a themed shelf for once instead of my collection scattered about between. It matches my Star Wars - Imperials base diorama shelf in the sense of just being one continuous theme. I moved my Jurassic Park/World stuff around, more in the living room and where I had my Megatron shrine is now a Jurassic Park/World shelf. I'll get some pictures of these in the future at some point. I just wanted to showcase how my TF collection is growing substantially from its humble beginnings.
