I don't think they are, if they were you'd think the news would be easy to find on a ton of sites on google, especially the main news sites and channels for movies, you'd think they would have said something, so its probably false, also if they are making a sequel like supposedly dragon ball evolution, I can tell you right now it will flop, sure godzilla 2014 maybe made alot of money but people that watched it hated it, same has happened with alot of movies. just because people pay to watch something doesn't make it good, you have to watch it to love it or hate it which you have to pay to do, hollywood producers don't seem to get this at these times and make sequels while not listening to the fans or critics and just the profit they make 
Yeah it seems to happen a lot of times. I actually found the movie rather disappointing but there might have been people who enjoyed it... meh I just don't care if it has 3 sequels or 8 lol
Edit: Dragon Ball Evolution 
Edit2: Off-topic again XD
