This is a simple compilation of console exclusive game sales from September 19, 2009 to January 2, 2010. All older titles are included, though just rough estimates (please inform me if I missed anything). I count timed console exclusives (Star Ocean 4, Final Fantasy 13) in this list because their rival console counterparts haven't been released yet. I started the count on September 19 because that is the week right before the launch of Halo 3: ODST, which is important to include in this list because it is the highest selling console exclusive of the season; basically I consider Halo 3: ODST as the unofficial start of the holiday push.

As is obvious, the 360 has fewer console exclusives still selling, but each of them sells far more per title, resulting in a much higher total. Many of the older 360 console exclusives aren't selling anymore, in contrast to some of the older PS3 console exclusives which have seen a resurgence of sales thanks to the PS3 Slim, which ironically outsold the 360 hardware by a hefty margin.
Overall, despite the larger number of PS3 console exclusive titles and hardware selling 25% more throughout the holiday, the 360 still sold 20% more copies on console exclusive games this holiday season.
Interesting notes:
1.) LittleBigPlanet is the highest selling title released before September 19, 2009, followed by Halo 3. Amazing legs on these games.
2.) Valkyria Chronicles, a game that received no new advertising, no bundles, and no price cut suddenly sold 253k. I doubt that this number is accurate, but if true, this is a huge win for SEGA and Sony.
3.) Lips has quite a following, apparently, closely competing with Singstar.
4.) Killzone 2 disappointing holiday sales, as it was released this year, because it was outsold by many older games.
5.) If we don't count Halo 3: ODST as a holiday title, the PS3 exclusives would outsell the 360 exclusives by 20%.
Edit: there, you have your console exclusive labeled. sheesh.
