IGN has posted their hands-on preview of Madden Ultimate Team, along with a couple of videos here.
"Okay, so it is true that you don't technically need to spend any of your own cash to build up your team, but it sure does make it easier. After every game you play you're awarded a certain number of coins which you can then spend on Ultimate Team cards. The problem is that the most coins that I've seen anyone get is around 100 and the cost of buying worthwhile card packs is insanely higher than that. For 9000 coins you can get a platinum pack (the best players in the game), for 3000 coins you can get a gold pack, for 1500 you can get a silver pack and then there's the lowly bronze which you should just steer clear of. If you play 15 games and do extremely well in all of them then you'll be able to buy one silver pack. That's a lot of Madden to play for a mid-level card pack. Of course you can always take the easy (and clearly more encouraged) way out and purchase the packs for Microsoft Points or money on PSN. The platinum pack will run you 240 Microsoft Points or about three bucks.
It's also a bit strange to see the cards that work their way into some of the packs. I bought three platinum packs with Microsoft Points on the debug online service known as PartnerNet (where there is no real money being spent) and found that my core of receivers featured a classic version of Randy Moss and three other homers rated in the 50s and 60s. It's clear that skill position players are a bit tougher to come by than an awesome right tackle; I had five or six of those."
