Scott thanx for the research.....I will play a T4 as soon as possible...the price is of no concern if it serves my needs as I have owned a T1/T2 so far.. I Look forward at this time for the S Series trickle down also.....I wish they would release both at the same time for comparison.....in the weeks to come we will see.... meanwhile the T4 release is only a few hours away !!
