IMHO, Investing in Cyberjaya has its own risks and rewards.

The pros of cyber
1.) A growing working population & tax incentives for foreign companies to operate here. Already have >50 MNC companies operating in Cyber.
2.) Good infrastructure already build. Road, Highways, drainage, Fiber optic cable, etc. MEX highway is a +.
3.) Government school, International School, University, Colleges already build
4.) Clearer blue print and development plans by setia haruman as annouced recently, future RM20bil investment.
5.) Better plan than other areas, due to having a single master planner.
6.) Developments in Puchong & Serdang have connected to Cyber.
7.) Quality of population in Cyber, mostly graduates and profesisonals. Potential of truning into anoterh TTDI, BU. Medium to high income group.

Risks
1.) lack of amenities and entertainment, but with D'Pulze shopping mall up, i believe more will join in, population attracts business, business attract population.
2.) Return on investment will be longer as it needs time to "move" people in.
3.) Higher entry cost coupled with a risk of sudden surge in property supply may pull rental down, but it depends on how strong the demand is especially when HP is already operating in cyber with not enough accomodation to supply at this moment.

In short, is an upcoming township, good for own stay and for investment may need to hold for a little longer for best return (provided you can rent it out at good rate).
