Surprise level: 0.
Console gaming is slowly dying in Japan in favour of the mobile market, mainly because people don't have time to sit down and play console games in Japan anymore. Being able to squeeze in a few minutes of play on public transit or during a break at work helps them. Konami is a Japanese company full of Japanese employees who pretty much exclusively care for the Japanese market. Any market outside of Japan is pretty much just excess to them. Ergo, if Japan is slowly bailing on consoles, Konami will follow suit. It also doesn't hurt that developing mobile titles is significantly cheaper and the fan base for mobile titles is generally far easier to appease than console or PC markets.
Is it a smart business decision? Maybe not. I doubt the mobile market will make them as much money. Do they care? Fuck no. Konami has never cared, at all, about gamers or the gaming market. They made a Machiavellian
boot camp for reviews of Metal Gear Solid V, just so they could
spy on reviewers while they played. They intentionally forced reviewers to censor negative commentary of their title, too. This isn't the first time they've done this, either. They have no integrity, and they haven't had it in a long time, and fans of Konami are either painfully oblivious to this or so apathetic as to warrant pity. When a company gives
so little of a fuck that they'll flagrantly institute boot camps for reviewers just to deceive you into buying their products--good or bad--do you really think they give a shit about you? Even slightly? Do you really think there's even a modicum of humility in the same company that scrapped Silent Hill because fuck why not?
Konami stopped being a gaming company a long time ago. This is just the formal letter of resignation because they've ridden their oblivious fans so long, so hard, that they're now starting to chaff and would prefer to target an even more gullible market than fan boys: Mobile gamers.
