For existing exhibitors the price went up for those that get a smaller tables or endcaps and may have gone down for the larger booths.
Previously the price has gone up from 5%-20% every year.
Looking at price changes from 2007 to 2008. The price is not based on when, but on who and when. The lowest end has been removed.
10x10 Regular - 2007 $1095 (early registration) - $1385 (normal registration) - $1520 (Last minute)

50x60 Island - 2007 $41,200 (early) - 49,440 (normal) - $54,380 (last minute)
50x60 Island - 2008 $39,000 (exhibited previously) - $48,000 (last minute - never exhibited)
Looking at the prices, singles, corner and end-caps (smaller booths) went up about 20%.
Islands and larger booths went down in price except pennisula's.
It now looks like they are rewarding re-occurring customers and newer exhibitors that want more than an Entrepreneurial booth.
The new $250 per company sharing cost is not surprising. The number of shared booths has risen over the last few years including several that are 4+ companies at 1 or two booths. If Gen Con has empty booths while at the same time 5-6 companies share a single booth it is reasonable to charge for multiple companies at a booth.
Though it has increased the cost of my booth I think this is a reasonable change. In the past there were 51 different rates depending on size of booth and when paid. Now there are 3 rates based on square footage: $11 (Entrepreneurial only 10x10), $13 (reoccurring - early) - $16 (everything else)
