Actually the PDF WSOP schedule is pretty detailed with regards to that. The 8PM Mega's will always be NLH, and will be $575, except when they are feeding into a 5K or 10K event the next day in another discipline. For example, if feeding into a 10K, Mega buyin will be $1,100 and play the 10K discipline, and if feeding into a 5K like Omaha for example, Mega buyin will be $575 and play Omaha. All other nights are played as NLH for $5K in lammers, except when it gets closer to the Main Event, they'll play for $10K in lammers.
Check the last page in the PDF.
