I haven't the slightest clue why people think 60% boards are overdone in the custom market.
We have had: the duck mini 1 & 2, eagle, viper, 356mini, kmac happy. That's all I can think of.
In terms of tkl we have: koala, whale, dolphin, unicorn, orion 1 & 2, tx87, Mira, 456gt, corsa, more corsa, corsa, did I mention corsa? Then there is also kmac, kmac, kmac, more kmac, kmac. I probably missed a couple of corsas and kmacs. Then we have the Janes, cheats, LZ, more LZ, even more LZ, a few other LZs and more LZ.... Do I need to extend this list any further?
The only thing that 60% boards have in large quantities would be the aftermarket cases, but frankly, those usually don't come near the quality of a true custom kit.
Who knows? Maybe the demand for even more tkl boards is that overwhelming and we need yet another.
But, in my eyes, rarely have I ever seen a 60%/65% which lives up to the standards of a real custom kit. Hell, I can only think of 2 60% boards which are mounted to the case instead of using standoffs.
