Here The Wall Street Journal Europe reports that what the two countries said was they needed more information about the details before making a decision and that they would have to put up for parliamentary approval any treaty which involved a limitation of sovereignty. I interpret this language as suggesting the government is less-than-enthused about the proposed treaty.
Hungary and the Czech Republic are half of the Visegrad group, the other two members being Poland and Slovakia. It is possible that the four members will attempt to coordinate their response to the treaty.
