Well, let's see what they'll do but I think that they won't be able to do it.
Case one: Readon Pro Duo will be in the lineup obviously (unless they're giving that thing a three months sale window which is very unlikely) and for some reason they've decided to not show it on this image which already makes it inaccurate.
There's also this:
AMD Radeon M400 Series, rebrands confirmed by drivers. Everything below M380 seems to be a rebrand in M400 series and I expect the same to be true for desktop R400 lineup.
P10 will be used for 490X and 490, P11 will be used for 480X and 480. 470 and lower cards will be rebranded from R200/R300 series with Tonga being used for 470 and Pitcairn being used for 460 (which would make it the longest running GPU in history probably).
