Ordering current Studio Display to get new model earlier

I am wondering if there is any experience on ordering a product before the potential release of new one.

Studio Display delivery times are mid march, which seams to indicate new model release.

So I am wondering; if I order I could potentially:

- get new model earlier

- lock current price

If any of this assumptions are wrong I can always return and order new model or decide to wait longer for the new one.

Thoughts?
