i was writing about it a long time ago in the challenger section on mtf
btw, as challenger calendar for 2012 is out for jan and feb
kazan, wolfsburg, florianopolis meknes and casablanca are cancelled... (at least comparing to last year)
in exchange dornbirn (austria) will be the biggest tournament of the first 2 months €106,500+H
while we're at prize money, challenger prizes not only don't grow, but usually go down! also, more players will have to be in futures in those weeks...
as for update, seems like other challengers fall out of the schedule
Not sure what I mentioned last time, but the calendar is up to March now, and these events are not scheduled (and were in 2012):
The only new event is this Austrian one
At least Sao Paulo money goes up from 35K to 125K!!! And Michael Russell is the top commitment so far.
From Nathii's list, yes, there are more southAmerican tournaments to disappear (also Moroccan) but it's also the period when there are most southAmerican challengers together with the end of the year, the rest of the year will be more in Europe and the USA, we'll see the situation there.
