When is the new game coming out?will it be region free or on the PAL version?what exactly is A-tier D-tier can you elaborate.Hakumen is a weird character don't know how to use his power.
New game is coming out on July 27th in the US.
PAL date has not been announced, but the developers have assured that it'll hit 'in 2010'. You may know that while BBCT came out in mid-2009 for US, it was delayed for many months for PAL regions, coming out in May of this year.
Hopefully there won't be that much of a delay this time around.
I would recommend getting a Region 1/ Region 3 copy. I don't know much about game availability in Pakistan but you can talk to PG member Amaga regarding this.
I might put an order on play-asia.com for a copy, like I did last year.
As for tiers, well, tiers are just user made lists that sort characters based on how powerful they are. Tiers go from S (the highest) to C or D (the lowest).
Tiers don't really matter in BB as everyone plays so differently. Don't pay much attention to them, tiers lead to mindless fanboy debates many times.
Haku-men is kinda weird, but he's the simplest to play and the closest thing to a Street Fighter character IMO.
