Do you know what annoys me?
When you write a really long response and it doesn't post and all you're left with is emptiness and apathy.
Well to summarise my "un-posted" response.
Earl Boen needs to retire, which is good for the franchise if it too is ending. It means we're not going to get really grating voice-actors.
Secondly, the open-ended conclusion I believe is satisfactory as a series finale, more questions are better than corny explanations that seek to culminate a series. Also open-endings don't discount the ability of a second season.
Thirdly, I believe we need a bit of time, and we're all used to waiting for new Monkey Island games. We're very patient. But with time we are more certain to have better graphics and better character models which I think have become a hallmark of the series. I personally love coming back to the franchise knowing that Guybrush will look somewhat different than before, be that cosmetically or stylistically.
I'd certainly like to see an MI game in the future look more like the E3 LeChuck's Revenge:SE trailer. That blew my mind.

Alas I had some really cool points but lesson learnt (the hundredth time now), I must definitely type everything in MS Word then copy/paste here. Stupid internet >_<
