"I see you like the 747..which developer you fly with? the other? come on! any simmer that has been on a 747 can tell their work is still cartoonish, its using gauges and graphics from fs2000, did you know that even Captainsim, the 727, 707 they are using the same gauges released by their first 727 back in ...when 2003?
Ten years have passed! reason? good developpers have also moved on to other things"

I highly doubt that as most FS2002/FS2004 gauges aren't compatible with FSX... The 747 of that developer is already quite old and they are making new V2 version of it.

Developers today utilize potential of FSX about as well as possible.
