question about my company acquired by xxx company

dear sir,

My company will be acquired by another company-xxx with similar business type. Right now, my PD date is March 2008. There are two possibilities about this acquistion:

1) the company still use same logo/name . I can get the salary from the same old company. my current company will be "a xxx company"

2) My current boss will be VP of xxx company. My current company will change the logo and I will get my salary from xxx company.

 

How those situations affects my 485 submissions? Do I need to H1B transfer or others? Thank you very much!!!
