I agree that they have be a lot more consistent with their releases of their games.
Square has had a massive exodus of talent over the years which has left them in a tough position now
Not as much I will say as Capcom, they lost Hideki Kamiya, Shinji Mikami & Keiji Inafune, and they all left Capcom and made better versions their Capcom created series, Bayonetta (HK), The Evil Within (SM), & Mighty No. 9 (KI).
Square still has game leaders in the company such as Nomura, Tabata, Yoshida. The main problem that I see, is that SE also has people like Toriyama & and I would hazard to say Kitase, that have lead teams with mixed results.
So we need to wait see where this is going as we are just reacting at this point and need to watch where this goes, they need to refocus their company and get things done. We also have to remember that Crystal Tools was a failure as a graphics engine and they needed to start from the beginning again when they made the Luminous engine, and FF14 which in 14's case people like it and that seems to be working for them at the moment from now, shown by the fact that there is a thread on this site for FF14.
SO LET US SAY IT TOGETHER!!!
PLEASE BE EXCITED!!
