Though the letter didn't bring any news (besides the Deutsche Telecom), it is a very straight and clear communication with one message to us:
"The MMP is still alive - stay patient until the USPTO has done its job (and we are confident, they will re-validate the MMP)"
As said before nothing new, but the tone of the letter is much more straighter than his last letter. If he would have written a few of those sentences in the last letter, I guess some/most of us would have been much more relaxed.
