I've always been tempted by Tau - but then at the point of taking it seriously, I always opt out.
I have a few bits laying around (I sold most of it to my brother in law as a starter army!) - If they redid them and made them look uber cool, I'd defo feel the need to buy them again.
IF May turns out to be true, could be bad for my wallet. But bad for my wallet is good for Gaming Figures
