It's not a matter of wanting the Asian market. They need it to dominate it to have a change at global perspective due to how much their e-sports infrastructure has evolved (it's still massively ahead of everyone else in terms of production).
StarCraft 2's scene was built on the foundation already provided by KeSPA (which rose due to the nature of PC Bangs in Korea). It is extremely unlikely it will have a scene like SC2 does.
There's a lot of news articles that the E-Sports scene in Korea is dying due to the major shift in technology (PC Bangs existed as a place for people to go and play games since many lacked the resources to play it at home). Now that most computers can comfortably run all these free to play things from home which cause the competitive nature with these games to decrease sharply. Brood War will be considered completely dead in Korea at the conclusion of this season's ProLeague tournament (which already suffered a compromise with a hybrid BW/SC2 format). Korea is really the target audience if you want to even attempt to get a professional scene like SC2 and BW alive and they're currently madly in love with League of Legends. StarCraft 2 already had a massive fanbase (TeamLiquid...also which was built on Brood War's foundations over the course of 10 years-ish) following it to allow for it to bloom into an international thing.
There won't be much hope for the vision they have.
It sounds more like just bug fixing and adding two features (saving to cloud and achievements) from the original client back when the original PC/PS version was released where as an HD remake would be almost like making a whole new game. Either way, I already bought the PSP copy about a year-ish ago and you can't really get more portable than that.
