ADC screens and the imminent 2013 Mac Pro?

Hi all, I'm thinning of finally retiring my old G5 tower and buying one of the new Pro's when they launch in December 2013. Ideally I would like to use my old ADC Apple 23" Cinema & 17" Studio displays (plastic case). The problem is going to be connectivity to the new Pro - I'm currently using twin ADC to DVI converters to connect my G5. The new Pro has HDMI or Thunderbolt ports only.

I would like to buy new screens at some point, but due to the high initial cost of the new Pro, I need to do things in stages, and was hoping to buy Pro first, use with my older screens for while with an adaptor and - then buy new screens in a year or so.

Is there any way around the issue ?

Any advice welcome. 🙂
