Yep, there's no reason for them to change (other than to make it better), because Internext IS the biggest show and whether people like it or not, they keep attending because everyone else is going to be there. Hell, I don't want to go to the Florida show (gripes about the layout of the show and the inept hotel staff), but I will because there will be people there that I want to see, talk to, and do business with.
It's like the big TGPs. It doesn't matter if they're hurting the industry in general, *their* pockets are getting lined and as much as people bitch, they keep submitting - so why change anything?
Change will only happen when either people stop going or something just as big comes along and threatens to take the crown.
I'm not sure there *is* anything that could come along that could rival Internext. So until then (and probably for a good long while), it's a matter of don't go and don't do business, or go and just deal with it.
