I just got my M&P22 today. It's a mate to my Colt 1911 Rail Gun. The lineage is unmistakable. They come from the same manufacturer if not the same factory. Of course, that's no surprise as they're both marked Walther. Except for length, the barrels are identical and except for the location of the mag catch and base plates the magazines are identical.
But are they actually Walther made Walthers? The following information comes from many hours of research and isn't conclusive. The evidence comes in the proof marks. There are at least 2 Umarexs. The parent is a german manufacturer of airsoft products. The other is wholly owned subsidiary based in the US that is an importer of Umarex products, Umarex USA.
Umarex in Germany owns Walther, Hammerli, and Rohm. Some names I'm sure you'll recognise. Now on to specifics. Walther is located in Ulm, Germany. It just so happens that the German government has a proof house in Ulm. The symbol for the ULM proofhouse is a single antler. Umarex is located in Arnsberg, Germany. The closest proofhouse to Arnsberg is in Cologne (Koln). The symbol for the Cologne proof house is a shield with 3 crowns.
Both my M&P22 and Colt Rail Gun have Cologne proof marks. Pictures of the Walther P22 I've seen show Cologne proof marks as well.

We know that Umarex manufactures 22lr rifles that copy the AR type rifle. They're reputation for quality in these rifles is not so good. Additionally, the quality in their airsoft products is spotty. I assume that Umarex is manufacturing the P22, M&P22 and the 3 Colt 1911 models in Arnsberg based on the proof marks and just slapping the Walther name on them because there are few gun manufactuers with Walther's quality reputation.
I have communicated with many folks over the interweb including some that live in Germany and they have come to the same conclusion. Unfortunately, I've yet to communicate with anyone that actually works at either factory to verify my theory.
Incidentally, the date code goes like this: 0=A, 1=B, 2=C.....
In any event, I love the Colt. It has had few ammo problem. I expect the same from the M&P22. So, in the end, who cares, if the guns work good.
