Hmm.. the Januray WD issue says specifically that the next Wd... IE, the Feb one... WILL be the 40k 25th aniversary edition.
Really doesn't make sense to have it as a LoTR issue in my mind given that.
I can't remember anyone having any speculations about a LotR release, the first thing I heard about it was what IanC just posted - curved ball indeed.
I do enjoy the miniature. Knowing myself I will probably buy 2 if possible, one for keepsakes and one to modify to hell and back. And here I was planning to make 2012 a low spending year...
