This is a thought I developed for some time now, and I guess it is more speculation, as this is not up to us, but Konami themself.
For those who do not know what crowdfunding is: Basically, a gaming/movie/music company wants people to give them money for a project (in this case, a new Suikoden). The company sets a minimum of total donations (e.g. 1 Million $) and the project will start as soon as this goal is reached. People make their donations and will get bonusses according to their donation. E.g. a 10$ donation will get you a discount if you'll purchase the game later on, a 20$ donation will give you a free digital copy of the game + discount on physical copy, 60$ donation will give you free artbooks, 5000$ names a SoD after you... and so on.
This is a method which becomes more and more prominent, especially in the indie gaming/music/movie scene. Examples are Iron Sky (movie) or the Angry Video Game Nerd movie. For more information: http://en.wikipedia.org/wiki/Crowd_funding
So this is the basic outline.
What I want to say: Suikoden is a niche series and every new entry to the series might be a financial risk for Konami: they can't predict sales, so they maybe want to save money which might decrease the quality of the final game, or maybe Konami will decide to not produce a new game at all.
But if they'd say "Hey Fans, we want to make a new Suikoden game for PS3. Production costs will be 10 Mio $, so we would like you to donate a quarter of it to get this game released and save its quality."
If you say there are ~500k people interested in the Suikoden franchise world wide and maybe 200k of themwould be willing to donate at least 5$, 1 Mio $ are a really, really easy goal to achieve, and I guess 2 Mio would be possible too. I mean 10$ for everyone is not much, and you'll even get something as a reward.
Additionally, they could use this for other projects. An official Suikogaiden translation for PSN, PSN releases of all old Suikoden games... whenever Konami needs money, they could think of a way to minimize risk by fundraising. Or only EU/US Konami use this to get money for translations.
BUT (and this is a really big but) - this can only work if Konami would be more open with fans and be willing for real discussions with fans. Fans are only willing to give money when their opinions are heard and they can somehow be involved in the creation process. Fan projects like KC_MCDOHL has started on Facebook and fan sites like suikosource will of course help in the process.
This has become a rather long post and I hope it is comprehendable. This is all a theoretical discussion, because in the end, it is up to Konami to do something like this. Sooo... your opinion?
