Zero problem with early access from my end. Everyone is clear what is being offered, like any product, swish it around and decide if you are up for it or not. It's no trick.
However I can see some issues:
1. Bad initial word of mouth by impatient gamers could be troublesome. However if we were the accountant for the Dev's, they may say "we have to do this to keep the doors open and develop unique games AAA Dev Teams won't make". Which is logical to.
2. For multiplayer games (Thinking more of DayZ types) that you will have a lot of people that have already played the piss out of a game before it is released. When released A. you have people that are superior to you or possibly ghost town like feelings. Not a brand new fresh release.
3. EA games going on sale while still in EA. That one now makes me wait for deals in EA even, lol.
