On the contrary, I think the fact that the EAP customers are clear on the status of the player's development - and that they can expect to see problems - is part of the point. They are getting a wider sampling of users and environments by offering people the option to buy the player early in spite of the fact that they are still refining the firmware, and using those additional people's feedback to help determine when to release the player to the public. And those consumers are going in fully aware that they are only getting the player early because it's not done, rather than getting it early under the misconception that it's done when the manufacturer knows it's not but wants to hit a pre-determined delivery date.
Another reason to keep the EAP small is support: they can expect questions, comments, concerns, and assorted other chatter via email and phone at a much higher volume relative to the number of units sold under these circumstances, so keeping it small allows them to keep a good handle on the situation.
Now, to jump to a separate (but still relevant) topic, I've received OPPO's blessing to post an EAP-oriented version of the player review that I've been developing over the last few months. That review can be found here. It will be edited over the weeks ahead as the EAP progresses.
