Yes, Warlord Games makes Landsknechts.
I was in on that campaign with 200 bucks for the plastic set when it was still Pro Gloria on Indiegogo. That campaign alas failed, and they sold all of their metals and the existing concepts to WG who luckily published that a year or three later, adding arquebus and double handers later.
Still...
I am quite unhappy with many of their design decisions. The pikes do not look like those actually used, the heads are only partially usefull (thanks to Steel Fist for their metal versions), the Katzbalger are too large, and some of the armour is simply ahistorical. It is good to have them, but these sets fall far short from what they could have been. Repeated twice.
The fashion of Landsknechts certainly changed a lot over the years. In their first one and ahalf decade, from 1482 to 1493, they would look not far from the "Burgundian war" Swiss, who trained them and formed integral parts of their units (unsurprisingly, as the Swiss was formally part of the Empire). We do have pretty good depictions of Swiss and Landsknechts from around 1499/1500, when they battled it out in the Swabian wars, in addition to other paintings and sketches. A totally different fashion style.
When Landsknechts show up on paintings over Ravenna, Guinegate, or later Fornovo, they are again transformed, and probably in their most famous era. The Swiss would look similar, if in details decididly different, and even the Italian, French and Spaniards tended to look not far off. On the most paintings of Pavia you cannot really differ between Swiss and Landsknechts, unless you look for beards or other details. Looking at the paintings of the invasion of Tunis 1535 we again see many differences, and here Spaniards and Landsknechts look different.There are also fine paintings showing the imperial army on the march towards the defence of Vienna in 1532.
It would be here where the Conquistador sets kick in, and we can probably backtrack them to the late Colunella era. With the right heads and weaponry I would use them for the campaing from Pavia over Rome/Naples to Vienna and Tunis. I will see how good they mix with the WG plastics and metal parts once my preorder comes in.
Later Landsknechts, for the Schmalkaldic war of 47 and their later mercenary usage in the French WOR, would again look different, with Pluderhosen, wedged armour, and the felt hat (taken probably from the Stradiots) showing up - which would be pretty ahistorical for anything before 1540. Around 1570 the Landsknechts - as defined as self-regulating pike units - started to vanish and would only exist in name and memory by 1590.
So, why do I want Landsknechts for the only era where a set already exists? To supplement them. The WG landsknechts look a bit stiff, even when wielding arquebus or swords. Some of their armour (wedged plates) needs work to make it bearable, and many of their heads are useless - I am REALLY looking forward to put WA-heads upon the heap of bodies I do have. More important, there are no Landsknechts save the metals from Foundry or Artizan that can be used to model a push of pike or even a standing pikeblock (ad depicted in many contemporary engravings). I am looking forward to French or Italian style heads - head variety is one of the real great strengths of WA to create these units. My personal focus is on the 1515 to 35 era.
That said, and coming back to the "Malta"-posting - the siege of 1522 of Rhodes was at its time as famous as Malta fourty three years later, and was commanded by a man who was himself soldier by the also famous siege of 1480 forty two years earlier. The besiegers would be the same that conquered Egypt a couple of years earler, that had taken Belgrad the year before, who would crush the Hungarian army four years later and who would fail to take the breech they made into the walls of Vienna in 1529, faced off by Landsknechts and Spaniards.
So I am definitely also rooting for Ottoman forces of the 16th century.
