The video game reviews online for WWE 2K15 have been critical of the game but Dave Meltzer reported this week that it should still be a good year for the game business-wise since it's on all four consoles.
Here is the schedule with updated dates for Brock Lesnar appearances on Raw:
12/8 - Greenville, SC (Slammy Awards show)
12/29 - Washington, DC
1/12 - New Orleans
1/25 - Philadelphia (Royal Rumble)
1/26 - Hartford (post-Royal Rumble Raw)
He's not listed on the final Raw before the Royal Rumble but I wouldn't be surprised if they added him at some point. He is not currently scheduled for the WWE Fast Lane pay-per-view in February in Memphis.
The Wrestling Observer reports that there were plans for Paul Heyman to return in Tulsa to build for Lesnar's return the following week.
