Is Playfish's latest 'player research session' a play-phishing scam?

Playfish Amazon voucher interview offer
It might be too good to be true, but today, it seems that Playfish, the maker of popular games such as Restaurant City, Pet Society, and Hotel City -- sent out an announcement to players that says it's offering $80 USD per person, in the form of an Amazon Gift voucher, to participate in a "player research session!"

All it wants from you is to make an appointment to talk to them over the phone, for one hour, while you play their games on Facebook. In exchange, they want your name, age, phone number, and time preferences. That sounds like phishing doesn't it? To top it off, they already have your email, and if you respond, you're confirming that it's yours. So normally, an offer like this reeks of scammy spam, and if you're smart, you'll delete it and move on. But this one looks too perfect to be fake; it even includes links to Electronic Arts' (which bought Playfish last November) Terms of Service and Privacy Policy.
Electronic Arts and Playfish: Play Games, Give Feedback
Players who got this notice are folks who signed up for an email subscription to the official Playfish newsletter, and this offer isn't limited to the United States either. A different version of the letter was posted in the forums by a concerned player, and that one is offering to pay with an £80 Amazon Gift voucher. £80 converts to $127 USD, which is way more than the offer I got. The discrepancy is enough to make me suspicious, but I did sign up for it. If anyone has any of these emails, I encourage you to share them. Other than that, we must wait for Playfish to confirm if these emails are genuine.

The person who posted her letter to the forum has caught the attention of a moderator, so I recommend checking in on this thread.

UPDATE (7 PM): A Playfish rep confirms that this offer is not spam and is, indeed, legit.

"This is a legitimate offer that we sent to a random selection of players from throughout the Playfish community. Since Playfish was founded in 2007, we've continually sought feedback and advice from our worldwide player community to help make our games as fun and compelling as they can be.

This particular survey is seeking similar player input but since it requires more time of players we felt it was appropriate to reward them for their assistance."

So, if you get an email with this offer, you can feel free to take this survey and in return, you will be compensated with an $80 Amazon credit.
