TO of Ovino (a staple among the European tournaments) said that come the XI edition this September he's going to relegate Vintage to a side event on saturday concurrent with Legacy main event.
In 2015 TO started running a second somewhat smaller event called Ovino Spring. Vintage in the 2016 edition of this one had an attendance even lower than Old School due to being placed on an unconvenient day and other events in the same period.
Expanding on the state of Vintage in Europe would probably require an entire post on his own, I just wanted to ask some help from fellow players of the same continent that are about to lose one of the majors.
Also this is my first post where I'd like to express my thanks for all the insight I got from TMD and his members.
