We will see, wont we? 
Indeed, I guess. I take the above statement from this post made by theymos himself:
I expect that (especially after all this time) most people will be disappointed when the switchover happens because there won't be any major feature improvements over the current forum. My huge list of requirements will be met, but there's nothing groundbreaking in there. Building something (a little more than) feature-equal to SMF (which has been in development for over 10 years) isn't easy. But the new forum software is much more extensible and secure, so any future enhancements should be much easier to do.
I simply wouldn't want people to get too overexcited about the change. It does stun me slightly that the site would pay $1,500,000 for a software package that won't (at least immediately) offer any real feature improvements. However, each to their own, and as previously stated, the funds need to be used somewhere, so why not upgrade the forum software to the best available.
