Role of Developers in ECC 6.0

Hi Gurus,

Our company have recently moved from 4.7 to 6.0.

1. What are the steps/points to be taken into considerations after the implementation, taking developer view into consideration...

2. In terms of tools, what 6.0 has offered us, apart from traditional abap programing...

3. Heard the thing that developers have more restricted use/value now in comarison to 4.7, are v , programmers in a danger of extinction, literally..

Thanx,
