dudes we already have a 727 type aircraft... I find the vote for the Tu-154 to be incredulously redundant... If i was running captain sim I would most definetly not make a repeat of practically an identical aircraft within the same 1-2 year time period.  making a 727 and then a 154 would be like making a DC-10-10 and then a DC-10-30.... Rubbish! common people. seriously lets see a bit more diversity in aircraft type/market/purpose etc.  

We need CS to make a good 777 (which they are), a good regional jet such as CRJ series, B717 etc, an older 737, and an MD-80 type.  All of these addons in the market are sorely outdated and CS should make new ones.
