GDP revisions are oft times shrugged off as a look through the rearview mirror, but this time the look back is worthwhile since it's bound to be brighter than the earlier view.

First-quarter GDP, reported at 8:30 a.m. ET Wednesday, is expectded to have contracted by 0.2 percent, but that's an improvement over the previous revision's contraction of 0.7 percent. There had been concerns a tough winter could have made it even worse, with a decline of 1 percent or greater.
