Hello all, while this is not my fav speculative thread, I'm another fanboy waiting for an new rMBP since erroneously I sell mine and intended to replace it with an iPad, you know...
Sometimes I seek rumors where it's more probable you can find one good, but a BIG WARNING, the rumors I collected comes from an anonymous source who posted them at some forum which ends in .onion (Tor Hidden sites, or something like Silkroad for rumors). most rumors there are 99% waste, but sometimes an source is consistent and coherent with expectations, this is the case of the source that talk about Q3 for new Macbook Pro's release.
the same guy also tells about the new keyboard, don't have big speciations on its OLED, its more a way to illuminate it on a very slim surface, he think this OLED isn't graphical but only simple drawings printed not electrically generated graphics (programmable) as the OLED on the Optimums Keyboard, but don't disappoint yet, this Black Stripe over the keyboard not only looks terrific, but actually improves the KBD functionality, as the symbols light-up and change in color (white, red, green, blue), its also a capacitive tactile panel, with GESTURES enabled, you can: touch the screen dim icon and swipe left or right to Dim the screen, same with volume icon, also you can use it to go forward and back on the safari browser, he stands only has seen some printed material but don't seems the icon are pixel-generated (editable/ animated) but simple printed patterns with OLED ink, the good news is the same function stripe will be available on the next wireless keyboard to arrive with the updated iMac.
