EA won't get any money no matter WHERE you buy it, since EA didn't publish it...
Last month this statement would have been correct. Vivendi's deal with Valve ended on August 31st. They signed a new distribution deal with EA in August. This is the first release on that deal.
I saw copies of this in Fry's the other day. It's in a fairly thick DVD Keep case. Dunno how many discs it has, five at least I would imagine, perhaps six if HL:Source is on there too.
But the packaging doesn't give any indication of a publisher whatsoever. No EA logo, not even a mention of EA in the fine print (that I could see).
