i'm curious what facts you have to back up that statement.
hopefully you are not going to say "they use the same pattern as the continental that is X years old blah blah"
Well, it is a 12 year old design, and looking on Gislaved's website doesn't show that the actual compound has not been updated since that time. It's lacking either silica, rapeseed (or canola) oil or say Bridgestone's multi-cell compound. The website says it 'incorporates the latest technologies' but the accompanying pdf files does not speak of compound at all but of 'Sharp Angle Shoulder Design' and '3D Stepped and 3D Sinusoidal Sipe Technology', both of which are old, fairly basic tech. It does boasts using an asymmetrical design, which is a good thing because when Continental released the WinterContact SI in 2015, they said "According to Continental Key Account Manager Ryan Bradshaw, the asymmetrical tread pattern proved superior in Continental’s testing".
Does it use a old Conti thread pattern, yes, is that what makes it obsolete, no.
When the ContiIceContact came out in 2010 it was a great STUDDED tire, and won many comparisons for the next 2 years. Not sure if the the person asking about these will run them with studs or not, but most do not. Running a studded tire without the studs reduces it's ice traction tremendously.
In 2015, Continental came out with the WinterContact SI, the press release said that the "Si uses “+Silane additives,” a proprietary mixture to improve wet braking, and complex traction grooves to pack and bite into snow." Silane is a variation of silica.
in 2019, Continental came out with the Viking 7, in which the person in charge said "He said the new design offers significantly improved ice braking, noise and dry braking characteristics with similar snow traction and snow handling when compared to the WinterContact SI it is replacing.'.
So that places the Nordfrost 200 as two generations behind even in Conti's product portfolio.
this is false.
Yes it's old thread patern (one the best)
But the technologie is updated on those one.
It's one of the greatest snow tire out there... Not the best on ice but most of the time it's snow traction you need.
Is it a good tire, yes. A 2018 tire test shows it's a fairly good tire - when used with studs!

Not sure where you're getting the info that 'the technologie is updated' from, but it's not on Gislaved's own website.
Ice is much more dangerous then snow, snow if fairly easy to deal with, use large voids, z sips and traction grooves and you're pretty good to go; you pack the tire voids with snow, snow grips snow and you have traction. Ice is very different and much more dangerous and that's where proper compound comes into play, and this tire just doesn't have what it needs to deal with that without it's studs.
