This is probably going slightly off topic but there has been news going around these past few days about samsung coming out with a 5.8 and 6.3 inch phone/tablet. This line is expected be called the "Mega" smartphone line. If this is believed to be true I think that this would be a acceptable replacement for the SGP line. The screen size maybe bigger but the overall size may just increase just alittle. This has been done with the SGSIV.
The screen is bigger but the footprint is about the same.This would still be smaller and more portable than the current galaxy tablets which range from 7-10 inches. These products are expected to be announced at two separate events in May and July. Now what Im thinking is that the 5.8 inch device is the Galaxy Note 3 and the 6.3 inch device will be a galaxy tab. But according to this article it will be a new line of products from Samsung. Here is the link to the article
