So it looks like the match play is on the move again in 2016:
New locale: Austin TX
New sponsor: Dell
New date: late March, after Bay Hill and before Houston
New format: 16 groups of 4 playing round robin W-F, group winners advance;
Sweet 16 and Quarters Saturday, Semis and Finals Sunday.
That way, it's not a one and done for half the field, which is at least a good thing for the sponsors and TV. However, adding an extra round will always make scheduling difficult, as any bad weather from Friday on almost guarantees a Monday finish.
