How long did it take? People complain that Nintendo only announces games in a short window, then they announce games that won't arrive for some time and people still complain.
People want a steady stream of high quality titles from a variety of genres and sources. Companies that don't have enough in the pipeline generate anxiety about their medium/long-term plans. Companies that announce too far in advance generate frustration with existing droughts.
You would be surprised what some others have posted.
I'm sure they did, many people are chicken littles, but in terms of actual serious, ongoing complaints, first party titles were never one of them.
I think some actual ongoing, structural questions are:
Software
- Will Nintendo produce software to appeal to <group x>? This would include releases in genres <xyz>, existing IPs <a> <b> <c>, and new IPs?
- Will Nintendo avoid droughts by having a constant pipeline of releases?
- Will third parties produce high quality ports or original content?
- When the new consoles come out, what will happen to Wii U?
- With certain "casual" genres having been partially or totally subsumed by mobile/social gaming--and we're seeing this with the weaker reception of Brain Training, Nintendogs, etc and a general collapse of the casual/low-end titles, including collapse of movie games, fewer licensed children games, what effect will this have on attach rates and general ecosystem health?
Hardware
- Is the Wii U a well-designed piece of hardware, or will certain bottlenecks hamper software through its lifetime? Is it future-proof?
OS/Service Model
- Will Nintendo achieve best-of-breed or competitive service/OS features? This would include matchmaking, leaderboards, voice chat, friend interaction and chatting, demos, one-button purchase conversion, screenshot/video content, awareness of new and upcoming content, different purchase models (DLC, season pass, freemium models), ad-supported gaming,
- Will Nintendo attract digital content and present it in a consumer-friendly way? Why should I buy on Wii U instead of <other platforms>
Company
- As mobile/social exert significant downward price pressure on software, will Nintendo's margins decline? What will Nintendo be able to do to counter this?
- As a VERY Japanese company in a world where Japan is increasingly less relevant, is Nintendo missing certain connections or perspectives necessary to compete in a global marketplace? What are the effects of certain policies like pursuing 3rd party relations in Japan over US, having decision-making in JPN rather than US, apparent lack of interface with major middleware/engine providers, region locks, localization of first/thid party software?
- Does Nintendo understand how to leverage social media/mobile to promote their content?
I don't think "Is Nintendo going to keep releasing games?" or even "Is Nintendo going to keep releasing good, popular games?" were ever serious questions.
