The commercial/business areas are supposed to be where the education tower is going mainly. I think specifically they see that as a financial / education district. So basically where the bus loop is now and then the strip of land bound by 104th north, 102nd south, City Parkway west, KGB west.
A little bit of extension across the street to the development on the Canadian Tire lands, then more commercial/business in the strip bound by 102nd north, 100th south, Whalley Boulevard east, KGB west (where the strip mall it, Kal Tire, Staples, etc.)
The final key business / commercial areas are right around Gateway Station, and then from King George Station (Hub + Holland Point across the street) to Surrey Memorial (innovation boulevard).
I have yet to see any real concrete plans for anything on the Surrey Central plot of land other than that pie in the sky tower where the old Best Buy building is located, but that is the final commercial / business development area.
Everything else = condos + residential. So where Evolve and Wave 2 (I know that's not its name) is being developed, all that area is basically condos. Most you'll likely get is street level retail and maybe a few podium commercial / business, but nothing substantial.
Positive thing I would say is that all the above commercial / business "strips" of land are not close to being developed, and all the areas where condos mainly will go in is ready to be developed today. So you'll likely continue to see a wave of residential developments bringing the area to a critical mass where the commercial / business strips will begin to be redeveloped later.
/above all speculation and educated guesses + references to the area plan so prone to drastic changes...
