As noted above we're gonna have election in April. I was looking around for voter preferences, I really have no idea these days where to find such, but came across picrel on this site:
https://partpreferencia.hu/

To sum it up:
Essentially 5 parties has any level of chance to get into the parliament. Reps can be elected directly from constituencies and through party lists but party lists has a 5% threshold. So as a "full" party only 3 has a real chance.
The variation in the result - some pollster predicts Fidesz others the Tisza will win confidently - is probably due to political bias. I've no idea which pollster is in the pocket of which party.
The parties that contest for the 199 seats:
Fidesz-KDNP - the ruling party, for 15 years, Orbán and co.
TISZA - the collector of opposition voters, led by Magyar Péter
DK - remnants of the old socialists, MSZP
Mi Hazánk - right radical opposition, the succession: MIÉP -> Jobbik -> Mi Hazánk
MKKP - the joke party, or as started such

So. Restricting it only for sure voters.
Fidesz might get 40-50%
Tisza might get 40-50%
Mi Hazánk will get in, but remains a small party
DK and MKKP probably won't get in, perhaps they'll get couple of reps from the constituencies

The system favors the winner, it's easy to get lots of seats and even 2/3 depending. In 2022 the Fidesz won 2/3 wit a 52% (constituency) and 54% (party list) result. I don't expect this good result from either parties.
Weirdly enough even the most optimistic prognosis towards the Fidesz claims 51%. The most pessimistic 33%. This is a wide difference.
As for Tisza the variation is between 39-53. This one is tighter, but still.
We can conclude that there is no sure indicator who will win. The pollsters will keep this trend up and their biases because they are part of the circus. Last time all of them predicted big win from the opposition just before the election, even the Fidesz polling and whatever companies. I think they wanted to scare those who hates the leftlibs to go and vote for Fidesz.
Not sure what's the script this time.
