I wouldn't jump into conclusions yet as to Constitution being a primary stat for the Swordmage as many people on this thread seems to be implying.
Take a look at the Paladin... no, actually, take a look at the Warlord, Ranger, Cleric, Warlock and the Paladin. They all have at least 2 primary stats that when you select a build makes use of one of them and the other turns out to be rather redundant.
Just because the pre-gen character has 12 in Strength it doesn't mean that Constitution is a primary stat. In fact, Rich Baker said on that WotC thread (Source) that Swordmages likes Str and Int alike.
