iStipper has never prodced cards in a higher resolution than they have been recorded in.
( except of the VG Classic collection, that is the only product that has been upscaled to a higher then recorded resolution )
The Most current Information I have from the team is that they are recording in 5K
and producing 4K, 3K, 1080p and 720p product from the 5K recordings.
With the most current equipment they have, it takes them well over 12 hours to process a card.
This means, the production team makes the required edits and adjustments
then clicks the Process button, and it takes 12 hours to see the finished results.
When they first produced 4K, the higher bit rate took over 24 hrs to process.
iStripper is producing 30 minute long video every day.
it's not like a commercial or a tv show or a movie where they have days, or weeks, Months or years to work on the final product.
The Team is pumping out 4K 30 minute length video in less than a day.
Until current computer processing power quadruples, and the price becomes affordable
I believe 4K will be the Limit of the iStripper product for the foreseeable future.
There also has to be a user base capable of experiencing the new resolutions.
if you look at the collected Stats from web users around the world,
The Screen Resolutions being used are actually Dropping, not Increasing.
this is because more and more Mobile users are replacing the traditional Desktop users in volume.
But if you only consider Desk top / lap top users
1366 x 768 tops the list, followed closely by 1920 x 1080
these two combined Make up 60% of the users
Lower resolutions make up about the next 30%
and about 10% fall into the higher or Unknown resolutions.
This is one site you can check stats at, there are many others.

4k will be the upper limit for a while.
Some math...
Average Card size in 4K = 1.8GB
360 cards a year x 1.8GB = 648 gigabytes a year
if you plan for the Next 5 years, that's 3.24 terabytes needed for the Cards.
add another terabyte for the photos and videos.
So between 4.2 and 5TB should be enough storage to last the next 5 years for iStripper
For all of the Previous content up to today,
I'm using just shy of 4TB for all of the iStripper content.
An 8TB or 10TB drive should cover the past, Current and the Next 5 years
Also remember, that you should have a back up plan.
so instead of just One drive, Double up, or even get a third.
Use One, and use the other(s) for your Backups.
