if you mean next 5 years, Elmina will be similar to Denai Alam as residential area.
If you mean next 10 years and central park/mall/MRT ready in use, I believe Elmina can do better. 
It's a well plan township development.

That's what my retired parents thought when they moved into a property in bandar botanic. It's was a long highway ride but no jams back in 2005-2008. Then hoards of developers story building along Shah Alam and now it's a bloody nightmare to drive up and down kesas. Moral of the story, enjoy the quietness and jam free lifestyle until our local councils allow over development. 😀

My advice when buying sime Darby property in Elmina, ask if the contractor whether is Kimcon. If yes, dun buy that project.  They famous with their lousy material using for water piping. All their toilets leaking badly.

actually elmina is strategic if u r familiar with that area.

1) kl sentral can drive or take mrt at sg buloh
2) new township but can pinjam bukit jelutong/denai alam/shah alam. all within 10km
3) hospital shah alam or sg buloh or private near that subang airport. clinic denai alam got. kota damansara opening gov clinic soon
4) sg buloh very near, kota damansara/damansara also near
5) no need toll use jalan dalam to go to shah alam/sg buloh. damansara no need toll. unless going using nkve

The sd staff is lazy...they will ask u go to see direct contractor to fix it for faster response. That happened in BR. They will be 1 house allocated for the defect contractors. write in and keep bugging them....they will do whoever bugs them first...
