The news conference will take place in front of Angel Stadium, by the home-plate entrance, and will be open to the public. Those who can't make it can also watch a live streaming on MLB.com and Angels.com.
Owner Arte Moreno, general manager Jerry Dipoto, manager Mike Scioscia and several other current and former Angels will watch as Pujols gets fitted with his customary No. 5 jersey and Wilson puts on No. 33 (his previous number, 36, is worn by ace Jered Weaver).
Said Dipoto while announcing the two agreements from the site of the Winter Meetings on Thursday: "It's a very exciting day for the Angels community, for Southern California as a whole. And we're very excited about what this can do to our future and what it means to this organization today. An exciting day."
And fans are already showing their excitement.
Since Pujols came on board, more than 1,000 season tickets have already been sold and more than 500 online ticket packages have been purchased.
Pujols agreed to a 10-year, $254 million contract that includes a full no-trade clause. Wilson signed on for five years and $77.5 million, in a deal that includes a full no-trade clause in the first two seasons and a partial no-trade clause in the last three.
