I agree with Causeitso #388 is like the only one with a concept behind it. All the other logos follow the same formula :

Insert OMFG Cool free font + Blue Box

Do you really think that's what gap wants and their target audience are going after? Have you been at a GAP store? They love Helvetica because is neutral, just like their clothes. Helvetica is part of their identity, they are not just going to change that for the Cool font you just downloaded from freefont.com.
