Both titles will be playable for attendees.
Jump Festa is coming up in Chiba, Japan and Capcom seems to have something for attendees. According to Ryokutya2089 (who usually posts scans and details from Weekly Famitsu), the company will have four titles at the show which takes place from December 21st to 22nd. Two of those titles are apparently unannounced.
According to Capcom’s official website, the other two games are Mega Man Zero/ZX Legacy Collection, which recently suffered a delay into February 2020, and Monster Hunter World: Iceborne for PS4. The latter will have a new monster with Stygian Zinogre along with a new Guiding Lands region and other content in December. Suffice to say that there will be reasons to play both games.
However, the unannounced titles warrant more attention. While one game may be the recently announced Devil May Cry Triple Pack for the Nintendo Switch, there’s no confirmation of the same. That would also still leave one more title that is completely unknown at this point. Project Resistance perhaps? Stay tuned for more details in the meantime.
