I like to suggest to release new planes with the beginning of each new tour (maybe 1 (or 2 or 3

) plane(s) / vehicle(s)) independent of new patches / versions.
Why? Cause it would give us something to look forward for in terms of shorter periods of time and the whole 2 week thing would become obsolete (regarding new planes).
For me sometimes it's really hard to wait for new toys (yes I'm impatient).
But: would only makes sense if not to much has to be done to realize this.
