I agree with you DeffBossGitKrusha about the codexes. As far as my ork miniatures, I'm well behind you in points and I'm waiting to see how 8th changes the table top portion of the hobby on where to move next. I intend to collect them anyway because I simply love the models.
Once you get locked into a serious Ork collection the tendency is to push it as far as you can. lol.
But, I'm also at the point where I think I have too much and...less would be more. It would make my army more playable.
I've thought about starting pointy ears next edition and I still might but one thing that AoS did was create new armies for a new game. I'm hopeful we see that but I kinda doubt we'll see too much of it with such a huge line of miniature they already have and so many of them are relatively still new. Just looking again at AoS I might expect 4 new armies but it's easier in AoS where there's so much new to explore. But I'd say buying a new army released after and for 8th edition is a safe bet for not being left in the dust of old 40K. It is what it is. If the games fun and has fun missions and colorful armies it's going to be ok.
I think once we see the lay of the land I'll set out an army and make sure it's all fully painted and finished and just play that for the first 10 to 20 games then move up in points after finishing the next set of points. (Even my painted models need just a little more loveage, my whole collection is more or less levels of work in progress.) If I do E+DE+H, they wont even hit the table until they're all painted and finished. I did that with my AoS Bonesplittaz and it's been completely rewarding. Heck my team probably had the only painted army last Saturday at the tournament. (first one in 7 years and we took 2nd place 4 points under the first place winning team...nearly beat them in round one too.. Oh well, lol.)
