Depends on how much work they are actually doing on most of those PC ports, considering it's the devs doing the port, not Xseed. The only upcoming ones that we know they are actually doing a significant amount of work for are 3rd and Xanadu Next, while the rest is likely them pointing the devs in the right direction as to what people expect on PC.
Even with the 3 unnanounced games on the table, they're doing significantly less than what we knew they were doing last year around this time, which is why I honestly think they have other games to announce as well. Even the indies they have announced, the only one they're working on is Touhou, the rest are just them signing on as a publisher for them.
Beyond that, would we even be getting Akiba's Beat and Fate/Extella this year? The games aren't even coming out in Japan till late this year, would we actually be getting them the same time? I mean I know they have the PC ports and CS 2 coming up, but their summer/fall is just about a barren wasteland when it comes to releases they're doing significant work on. Surely they haven't been hiring more and more people just so they could publish games for people, nor do they seem like the kind of company that would up and abandon a platform when every other smaller company is still supporting it.
