A bunch of hapless idiots (to borrow from Bayer)...

• Milla is openly dissing Szolidaritás for organising the March 10 protest without consulting them,
  
• Kornél Árok organised that silly ersatz Opposition Round Table with left-wing parties only which instantly fell apart,
  
• for this (but officially for forming a party of his own) Árok was kicked from Szolidaritás,
  
• LMP, whose december 23 civic resistance protest was hijacked by the Socialists and Gyurcsány, now attempted to hijack the students' protest, for which the students openly blasted them...

I just don't know. I haven't seen a poll, I didn't hear people on the train talking about this, I haven't seen a single anti-EU graffiti (compare to the "D-209" and "Elkúrtad!" graffiti waves against former Socialists PMs Medgyessy resp. Gyurcsány) and people I know aren't a representative sample. If a majority feels the EU is picking on Hungary, then I think a wide majority of those is watching it with fatalism.

any electoral force will emerge from Milla/Solidaritas

We'll see what will become of 4K!, once they turn a party officially (always the pessimist, I won't hold my breath though).

will bring MSZP back from the dead

I don't think it was ever completely dead, or will become. They are well footed in a wide grassroots base, who won't go away even if what is left is a bunch of stupid and/or corrupt people. The best scenario would be to reduce MSzP to a dwarf like the unreconstituted commies (Munkáspárt). But, the likeliest scenario is what you write, a return of an MSzP who haven't learnt anything and haven't faced up to past mistakes.
