Is there a seperate thread for comparing the two? I feel like the 1/48s have a different type of customers base, unless it's someone that would buy both, like me. But I'm totally fond of the 1/48s due to the larger scale. I don't think that the 1/60s made it obsolete as much as I think that they've just exhausted it as much as they can. The only scheme that I feel they can do after the Max is the Kakizaki TV-1A, if they decide they can even sell it.
If I had to choose I'd always buy the 1/48s. But luckily I dn't have to choose and they added enough features on the 1/60s for me to want to buy them... mostly the tampo printing and the promise of having a complete line this time.
