So far there has been no news about who will play in German NT this year. Last year after WCH Guidetti said he will continue working with the same players, but the door is always open for other players who perform well. So my guess for the roster is:
Setters: Kathleen Weiss and Denise Hanke will probably be the main setters again. If Mareen Apitz decides to come to NT she also has a chance to be 2nd setter. Lena Möllers and Nadja Jenzewski are playing in the same club and there is no clear 1st setter, but Möllers is currently injured, so Jenzewski for now is starter in her club. I don't think either of them will be in NT, maybe Lena Möllers will get a chance but the others are better, she is just tall.
Opposites: No doubt that Margareta Kozuch and Saskia Hippe will be the choice if they stay healthy. Maybe Sabrina Ross and Tatjana Zautys can be invited again, but they are both already over 30, so I guess Guidetti will go with the younger ones.
Middle Blockers: Corina Ssuschke and Christiane Fürst are sure, but the fight for the places on bench is interesting. Nadja Schaus, Berit Kauffeldt and Anja Brandt all play in the same club and even there it's not always clear which of them is the best, they all have different strengths. Stefanie Karg can also be a candidate if she accepts the invitation. Kathy Radzuweit as usual plays a horrible season in our league, but whenever she comes to NT she plays much better, so we will see if she gets and uses her chance.
Liberos: Also easy to choose...Kerstin Tzscherlich will be first choice, the battle for the other places will be among Lenka Dürr, Lisa Thomsen and Janine Völker.
and now the big problem...
Outside Hitters: Not much choice here...Heike Beier is not playing well, Anne Matthes managed to get herself a place on the bench of an A2 team in Italy and putting up horrible numbers whenever she plays, Maren Brinker is supposed to be the best German OH but in our league she is definitely not even among the top 5 OHs. And there are no other candidates...Stephanie Kestner from Dresden was the best German OH in our league but she suffered a serious knee injury (once again) some weeks ago and will be out for 6 months. Regina Burchardt is sometimes playing well, sometimes bad, but I think she is not the kind of player Guidetti wants and also not really better than any of the NT OHs. Lina Meyer played a quite bad season after being the best German OH in our league in the last few years, her club will go down to 2nd league next season so I hope she will finally join a good club to improve her performance again. Sarah Petrausch is starter in her club, but also not having good statistics. In our Junior NT there also are no real candidates to play on a high level as OH soon...
So after all I expect the choice will be the same as last year with Beier, Brinker and Matthes.
