Well, As philG said, I see no definitive statement that Belgium will not attend.
Just that Joel Smets is standing down from a position he has filled so well, for 11 years, so he could better do his job ( for KTM) and have more time for his family and himself. A Great of our sport.
The Belgium Federation may well have some difficulties - many sporting organisations do. Hell, just after the Australian ISDE Teams dominated the event, the majority of funding for Motorcycle Sport was pulled, to waste, as usual, on our , largely, non achieving Olympics Team. Classic - gain World success, and the Tools in power ignore it, and waste public funds on no hopers.....
I doubt it will ever happen, but, if the major, long term participant Nations, if not All of the Nation's, all got together and nailed that Prick Luongo to the wall with a Genuine threat to not attend, unless adequate funding was given to All teams to attend, well, it would be a good thing.
That Pig is making a fortune from the MXDN, And the GPs. He needs to take care of the Golden Goose, and not fist rape it for the eggs as he has now for years and years.
As for every second year - fuck that - it's a view inevitably expressed the last few years by US fans with their losing streak, and it's just pathetic. I'm sure "you'll" win next year.
There were both the Motocross Des Nations and the Trophy Des Nations for decades, and countries attended. I'm surprised that avaricious mongrel, Luongo, hasn't thought of re-introducing the seperate 250 and MXGP events. Not that I am advocating it.
