Now Sony could waste time developing a forum that would work with the third party stuff but they would likely have to LEAVE lithium Servers and Are YOU willing to PAY the required Extra for running of the new forum technology and extra staff required to run it. PS+ is still not that popular and do you realy want even more adverts on the forum. I don't.
The Posted reason buy staff for being on lithium was that they do all the hard technical work and the mods get the tools they needed, the cost is shared buy all lithium forums used on sites.
They took a lot longer than I expected to get this forum to a stable state. an the Ex Top Mod said no changes in host for a long long time in EU. This means NO to non lithium forum apps.
This does not explain why lithium Mobile is not used unless lithium has stopped it.
But no one knows here if HTML5 support is 1 Year or 2 Years or next month.
Changing forums Would be a waste if HTML5 in browser support is this year.
The Browser released in both the PS3 and Vita was not as powerefull as had been openly tested.
Where that HTML5 browser went that was being tested on Sonys HTML5 test sites and HTML5test.com has not been leaked but it did not get released. on PS vita or PS3.
