It's not about 1:2, it's about getting a product who's quality matches it's pricetag. Finecast simply doesn't. If it was cheaper, then yes it would match (costs less, but the quality might be lower). It's been the main issue with metal vs finecast. Metal was almost always flawless, you got exactly what you paid for. Finecast is fiddly, breaks all the damned time and is often miscast. For that pleasure you also get to pay an increased price compared to it's quality metal counterpart of some two years previously.
That's a massive problem, and one they have solved by wedging their heads in the sand and letting finecast die off in the same manner as the Specialist Games.
I love 40k and it's bast*rd children, but some times the moves made by GW in there attempt to gain greater profits are staggeringly out of touch. To the outsider they appear to focus on making maximum profit for minimum imput, and aren't afraid to sacrifise it's core audience in an age where they are no longer captive. Unlike 5-10 years ago there are so many high quality miniature hobby companies on the market the only way GW can compete is to sell it's brand, not sell 3 boxes of space marines and then adopt a scorched earth policy on what has made the company successful over the past 30 years. They've completely killed off there once rock solid grip on the skirmish games market because it required effort. If you buy into the rumours, they are going to let fantasy slide off in to the same bottomless rocky abyss.
