I have a news tidbit for the upgrade prices for Fusion 2.5!
Until Feb 3rd 2014
The upgrade price from version 2.0 to Fusion 2.5 will be....
$39. After this date it will be $49
If you still have Multimedia Fusion 1.5 the upgrade is $69
If you have an older product you will need to purchase Fusion 2.5
If you have The Games Factory 2
The upgrade price from version 2.0 will be $49 until Feb 3rd 2014
After this date it will rise to $69
The price of Fusion 2.5 Developer will rise to $399
So if you don't own any products right now and have been thinking of getting the developer version --- You would save a bit of money if you bought it now and got the free 2.5 upgrade.
