Xara Xtreme Pro and my wish list :)

[BONES]

but when we talking about PRO level, with correct CMYK preview for offset pres, things are a litle bit different... and etc etc etc

What a load of *****! There are plenty of professionals outside the print industry. In fact I find most printers to be completely unprofessional in their inability to work outside of incredibly narrow parameters. I am a full-time, professional artist and I have never seen a four-colour separation in my life.

You are right but only for your point of view....
Tif is not so pro output but work not bad for you....

TIFF is one of the most useful file formats for print professionals, as Targa is for broadcast/video. It is incredibly flexible - greyscale, RGB, CMYK in anything up to 32bits - all with highly optimised, lossless compression.
It some print-shops that make everything such an ordeal - leave the slightest room for any error and a printer will stuff it up. Give them a giant TIFF of the finished artwork and they virtually can't get it wrong. For my money that is the very essence of a professional file format.

problem come when you need to create something bigger than A5, A4 or A3 size..... you can try it
then we talk about files with really giant sizes.... 100-150-200Mb each... OK
if only your cover is for print then no problem in print house... but believe me, Im senior designer/prepress master in such print house, and when I have to work on some magazine for example your cover with her 150Mb will be the last thing that I want to see.... then maybe you dont have idea wats going on, but I will say you.... then going some optimization... i.e downsampling of monster files...

Try working with 4k film frames at 24 frames-per-second. That's 4096x3112x24 per second. Even at 2k, half-float [16bit], we require a sustained data transfer rate of 850Mb/sec so you'll excuse me if the occasional 400Mb still file is hardly impressive in this day and age, where my new laptop came with 4Gb of RAM as standard.

Every one knows that graphics design work is times more than just illustration work, I mean that illustrations are just part of some design work, and will be better for us and for Xara all this proceses to be started and completed in Xara... is it so hard for understanding

Sure, but its not all about print, either. If Xara has to grow and stretch itself, I'd prefer to see some proper timeline-based animation added. It could be a wonderful paint/roto tool for the visual effects industry and an incredible motion graphics tool for the interweb and broadcast markets. Turning it into a boring old print tool would be such a waste in my view. It also seems to me that it doesn't do print stuff all that well so concentrating on RGBA work seems a natural choice.
