14 months seems long enough for me. I'm actually surprised they didn't show gameplay.

I definitely see how this can get some people confused when they have to wait like 6 years just to catch another glimpse of an announced new IP

You can say this all that you want, but the simple fact is that 2 years is not an average development time for a new IP this generation, not even close.

Doesn't seem too short to me. So by the game releases it will have about 2 years of development time. But of course I have no idea about game development so that's just me.

unless its not AAA. 

i see no problem with the timeline at all, just wait and judge the game when it releases. Like you are suppose to do, it seems people wana complain about anything at all anymore.

There're unfortunately not really a lot of AA new IPs to draw comparisons from this generation.

Or maybe we're just amazed at how things have turned out since devs have already explained costs and development time perameters to the gaming media for years now so when something gets created out of the ordinary it amazes them. 

Who's complaining? Sorry that some people are questioning the ability of a studio (or in this case studios) to create a new IP in 2 years in this generation where most new IPs take 3 or more years or so and are still often considered underwhelming.
