Short answer: it'll never happen, not in a million years.
But as a thought exercise, there are a whole bunch of different problems that would have to be overcome. Here are just a few of the more obvious ones:
1: As mentioned above,
poker is not a sport. That's pretty much the end of the line right there. But even if you could get past that...
2:
Poker is gambling. The IOC is staunchly anti-
gambling. Again, end of the line. But even if you could get past
that...
3: Poker doesn't have a "governing body" pushing for its inclusion.
Actual sports spend decades trying to get themselves included in the Olympics, and they require major campaigns with funding and lobbying to be successful. Poker can't even agree on a single set of rules for itself from venue to venue, let alone coordinate a campaign for Olympic inclusion. And even if you could get past that...
4: Poker makes for
terrible live television. Televised after the game has ended, with hole cards and graphics and all the boring
hands edited out? Fine. But for game integrity reasons you can't show hole cards during live matches, and you can't skip over all the boring hands. And if you can't show hole cards, or cut the boring hands, you lose your entire audience bar a few hardcore poker nerds.
