It would be pretty unreasonable to expect FFG to overhaul their whole Official Tournament Rules document so early in the game's life, to accommodate your 100pt build plus a new Millenium Falcon. If you look at closely at the pics for the Falcon, you can see that the Han Solo card weighs in at 47 points, and that's without any upgrades.
Who's to say taking Han in a 100pt match wouldn't be viable?You would probably still have room in your build to take another X-Wing pilot of some kind. Don't forget, as well, that it looks like the Falcon gets 3 Attack Dice at what we're assuming is a 360 degree fire arc. You don't need to worry about getting TIE's in your front arc anymore, just staying out of theirs.
With some evasive flying, your turret should help thin out their numbers a bit. Also, with 5 shields and 8 hull, it's not going down without a fight. It's easy enough to hit though, at Agility 1, so you may be making liberal use of your Evade action.
If anything, rocking Han in a 100pt tournament list puts you in a win big or lose big scenario, so your one ship could do well enough with minimal support, but if the opponent gets some lucky rolls off the start, you could be in a world of hurt if the Falcon goes down without taking any of your opponent's ship's with it.
