It all depends how much stock there will be of 42 inchers. If LG deliberately made this a niche product with little stock than it will be hard to buy. 48 inch for the first year was also an atrocious value compared to 55" and still was OOS most of the time.Not exactly a fair comparison as it was gimped compared to the bigger versions but the Samsung 43QN90A dropped fairly quickly after release last year.
People want value for money more than ever so the 42C2 might not be as popular as we think. Sure there is a lot of interest on forums like this but is the mass market willing to pay over £1k for a 42"? Guess we'll find out soon enough
