LazerLordz, the RSAF, like many airforces, is moving away from
single-role aircraft towards multi- and swing-role aircraft. So in
actual fact, the term "replacement for Skyhawks" is in itself,
slightly misleading.
It is indeed true that this NGF is to bridge the gap between the
F-16 and JSF. However, we also have to remember that our priority
is to bridge the gap, not just in terms of time, but also to
maintain the edge that we currently still have in the region.
Rafale is not battle-proven and the EF2000 has already met with
many hiccups.
Flotill 12F of the Aeronavale might have something to say about
the first part of that statement. 
[quote]When it comes to the Army, singapore may take their chances
with indigenous equipment.But when it comes to aviation, I do not
think the policy of the ministry is that of risk-taking, especially
when the risks do not constiute any radical experimentation in the
form of unknown technology.
On the contrary, the Super Skyhawk, F-5 upgrade package and the
choice of MPA are examples of that.
BTW, I'm an appreciator of old aircraft as well, although I prefer
the F6F Hellcat myself. 
Seen a C-47 flying before? Now that is a real classic, a must-see
by anyone who has any interest in historic aviation.
