Well I had read before the 360 came out that the faceplates (normally $19.99 (Microsoft first party ones)) would probably end up being pre-order bonus items. I didn't figure this would happen too much just because of the value of the item, I mean most of the pre-order bonus items are usually pretty lame (behind the scenes DVD's, Content CD's (wallpapers, videos, etc), and posters. Some times though you get better items like T-Shirts, or soundtrack CD's.
Well it seems I misjudged the companies as this week I've heard of 2 pre-order faceplates, and one free with purchase. EB Games has Sega's Full Auto up for pre-order with bonus faceplate.
GameStop has THQ's The Outfit available for pre-order with a bonus faceplate also.
Lastly Best Buy had one advertised in today's sale ad. Purchase Call of Duty 2, and receive a free CoD2 faceplate.
