Rumours say Bartók Béla Avenue's new name will be (probably) Horthy Miklós Avenue.
The first one was a famous composer of the 20th century. The latter one was the governor of Hungary between WW I and II ("slave" of Hitler).
Already renamed:
Moszkva tér (Moscow Square) ---> Széll Kálmán tér (prime ministeresident of Hungary between 1899-1903); because "Moscow is communist name", LOL. I think it's just a city. We also have Párizsi udvar, Mexikói út, Belgrád rakpart, etc.
Köztársaság tér (Republic Square) ---> II. János Pál pápa tér (John Paul II Square); just to annoy MSZP (left wing party), because formerly their headquoters was there.
Ferenc körút metro station ---> Corvin Quarter (new "city centre" of 8th district); simple business, the constructor of the new buildings/shops payed for the renaming
But we also have brand new names for the government offices (name of tax authorities changed from APEH to NAV, just to make it Fidesz conform with "National" name). What is it good for? Power demonstration?
