New players might not be able to make the comparisons, but they may find a particular thing (such as grid-intensive miniature combat) a turn-off.
On the flipside though, with the incredible surge in popularity of VTT's, grid intensive miniature combat is a breeze. I realized that I had no idea what folks were on about when they talked about "the 4e grind" when it occured to me that 99% of the mechanics of 4e were being handled by the framework of my virtual tabletop. It was all point and click. We never had these incredibly long combats because we could track and resolve stuff instantly using the VTT.
4e today would be reacted to quite differently I think, simply because you have such a large audience of VTT players that didn't exist in 2008.
