My feeling is not very strong as my life does not depend on this :P But I guess my expectation for today release was based on real information passed via Twitter and other media that they will spread the update this week and that it could have been last week but was postponed - from quite some time, they repeat early march... So if it is not the case, they should inform that to polish the update (they may have found some nasty bugs again this week that prevent the update to be released or they want an additional feature (I can see MMS currently being developped) to be included), so they need another week. And I will be clearly fine with it. I am pretty sure that the fact that they want the new update to be a reference point (not beta anymore), they have more pressure to release something with all beauty and magic
