Rarely post but would offer a little advice.
Given the almost universal unpopularity of the new system, hopefully you are also analyzing the actual impact of the changes made. Dangerous business model when you launch without any impact research.
Might want to do a quick analysis of the first two weeks impact in terms of listings, views, and purchases, and try and determine whether the cost of the new system is in actuality less than whatever costs were associated with maintaining the old marketplace. You can drive customers away quickly with no guarantee you can recover them.
I tried the new format but quickly stopped looking, basically the new marketplace is a pain and time sump. I'm out, imagine others are too. Will check back in a month or so and see if you have reverted or fixed. Funny thing is that fixed will end up looking a lot like the original. If it still is sub-standard, at that point I will not only be out, but gone.
Good luck, seems to me you need it.
