Honestly, I can't imagine Games Workshop lasting much longer. Cutting their losses with gameplay and focusing entirely on miniatures might be a good idea, but even if they did it, I'd expect they'd do it poorly. 3D printing technology could make that obsolete, but with a company as large and entrenched as Games Workshop, 3D printing technology could be used by them to put out miniatures faster and cheaper than anyone else can compete with. The problem I see is the pride of Games Workshop would likely lead them to try to charge as much as they currently do or more for said miniatures, and be out-priced by companies or individuals who actually play to the strengths of the technology.
It's beginning to look like GW are spending more time on renting out their IPs to digital variations of their products. There are a lot of video games and Apps hitting the stores lately, and with the latest change to the Fantasy tabletop line, I'd say it's a fairly solid indication of where their priorities are headed for the future.
But GW has been a part of my life for 30 years, it's hard to completely cut ties..even if it's just looking at long ago models that will never be painted , but thinking "maybe when I'm bored I will finish that dudes sword".
I need to eBay it, I need the space and the money. But actually letting go...tough it is.
I still have all my stuff, boxed up and hiding in a top shelf of the shed. Terrain, too... I don't think it's worth anything anymore.
