Aww, i'm incredibly envious of your Citadel one. Unfortunately when some of the first ME2 ones were being released our BB was terrible and I missed out. I have the mini version but...not the same 
And yeah...gonna be all over them as well. Especially iff they release some of the concept art ones we've seen and hopefully we'll see a team version for Inquisition as well.

And a Cullen litho of course 
Ohhh, if they have a team one for Inquisition... I'm already thinking about the parallel poster wall set-ups I'm gonna try and create between my ME and DA posters.
I'm really hoping they put DA:I artwork in the store, not just because it'd be gorgeous, but also because I need to balance out the sci-fi theme I've got going in my room right now. I've got all my ME posters, a few Star Wars posters (that I might take down), a couple of Halo posters, two huge Destiny posters, and then three more Destiny prints that I've been eyeing up for a while and am gonna order from the Bungie store when I can spare the funds (assuming they're available still...
), and then all the glow stars on my ceilings, and then the huge print of Van Gogh's Starry Night that I put behind my bed because I don't have a headboard. The only non spacey things on my walls is my Audrey Hepburn print, my limited edition Dishonored posters, my Skyrim map, and the Pokemon drawings/birthday cards my sister painted for me. :S So I would really like to balance things out.
Have you been on walls360? That's where I got my Legion, Garrus and "The Team" prints, although they're really more like decals, but they're really sturdy. I think they have prints of every ME lithograph that the Bioware store had, as well as some new DA:O prints of all the concept art for the origins. You can also get them in different sizes and they have sales fairly often. I have a theory that this is where Bioware Edmonton got their huge mural wall art printed off because I highly doubt that they actually painted it on, but I have no way of confirming that.
