1. No, we have none yet.
2. Only a fleet ACP or two have been to training so the first part doesn't matter, however the plan is to have two different fleets due to the differences so, no, the pilots will not cross fleets. It will be XL/XLS and XLS+.
3. Hard to say. The XL fleet is the largest at our company (some 105 airframes and 750+ pilots). Cessna stopped the XLS production line so only the "+" is being built right now. Until that point, we were selling off some of our older XLs and replacing them with XLS's. Will that continue with the plus? The XL/S is the best selling airframe we have so it is reasonable to assume they will eventually sell down the older fleet and build up the plus fleet, but we don't actually know the answer.
4. Other than the aforementioned ACPs, we haven't flown it. I have about 2500 hours in the XL/S and have talked to some folks who have flown it. Their comments were something like this...Essentially, the Collins is a much nicer avionics than either the Honeywell or Universal. It removes the whole glareshield annunciator system and puts the autopilot mode controller system up there, which they say is nicer. The center console is widened and there is now a knee panel at the bottom of the dash which all combine to reduce the amount of space in an already tight cockpit. They did not replace the butt-ass hard cockpit seats. The interior panels have been "rounded" more giving it a more spacious look and they say it should hold up better. As far as performance, it is an XLS with 200 lbs more thrust. They say it performs very nicely but is similar to the XLS. Biggest disappointment to me personally is that they did not build a similar wing to the Soveriegn or Encore+. There is no change on speed limitations as built and with a new wing, it could have been a .80 airplane... the one failing of this jet. Current limit is .75 and unless it's really smooth you really don't get over .74 due to the software driven speed warning horn going off.
As for folks commenting on the request, all I can say is that I am reminded of the lesson my parents taught me... that being if you can't say something nice to someone, keep your mouth shut.
