Yeah a lot of people are raging about it I couldnt even get in the beta being in the UK (signed up but did not get a code). I just hope the final game is good but I doubt they learnt much from this mess other than that they were totally unprepared.
Im sure it will be better at launch but I reckon there will still be issues and I am sceptical of the online being a major improvement over other fighters especially ones like Persona and KI which in my (admittedly limited) experience have a great online. At least they have a 9 months or so to get it sorted so hopefully they do just that. I would be more confident but Capcom have not exactly impressed me much with their practices the last 7 years or so.
That all said I do want to play SF5. I have not been this excited about the series since SF2 so dont mess it up Capcom.....or dont mess it up more anyway. I hear the Beta is postponed to an unannounced later date so maybe people can play then and they can get some data.
